		sarah pose la question : f(x)={x-2, x<-2        {x^2-4, -2_<x_<2        {x+2, x>2 find the range Penny Nom lui répond.
	A piecewise function		2015-04-25
		uday pose la question : f(x)={x^2+3x+2 / x+2, x(not equal to)=-1 {4, x=-1 how to find domain and how the graph looks like Penny Nom lui répond.

		srishti pose la question : A point P moves such that the difference between its distance from the origin and from the axis of x is always a constant c . what is the locus of the point? Penny Nom lui répond.
	Graphing piecewise functions		2014-03-29
		Rayven pose la question : Hi! I'm in eighth grade, taking ninth grade algebra 1. I'm confused as to how to graph piecewise functions. I know that you have already answered a question similar to this (I did my research first) but it didn't completely help me on my homework. I have to graph piecewise functions for the specified domains, and create a table for the absolute values. I know that two bars around a number means absolute value (two bars around -2 makes it +2) , but how do I graph and chart the absolute value for the following: f(x)= |x+3 | for -5≤x≤3 And then graph and chart: (on a separate graph): f(x)= {x if x≤0 {x+1 if x <0 thank you! ~Rayven Penny Nom lui répond.
	A function with 3 asymptotes		2012-10-19
		rimoshika pose la question : find a function that have 3 Asymptotic : y=x/y=sinx/x=-1 Penny Nom lui répond.
	An equation for a line with a changing slope		2009-03-21
		Ben pose la question : Is there anyway to write an equation for a line with a changing slope. e.g. A cell [hone company has a initial fee of 50$ paying for the first 100 minutes, the rate then increases to 10 cents per minute, then at 500 minutes the rate is 5 cents per minute. If so please tell how. Thanks Penny Nom lui répond.
	A piecewise function for monthly salary		2009-02-03
		Josh pose la question : A sales rep for a drug company is paid on the following scale. His base salary is $1600 per month. He is also paid a commission of 2% of sales over $20,000. When his gross sales reach $30,000 he is then paid 4% on the amount above that until his sales reach $50,000 after which point his commission becomes 6%. His commission reaches 8% when his sales total goes over $100,000 for the month. Set up a piecewise function for the information above. Harley Weston lui répond.
	Graphing a piecewise function		2008-08-12
		Shanti pose la question : how do you graph a step function or piecewise function such as u^2 if u is greater than or equal to -2 and less than 1 2- u if u is greater than or equal to 1 and less than 4 Penny Nom lui répond.
	Piecewise functions		2006-11-08
		Kait pose la question : We discussed how to graph piecewise functions today and I'm very lost!! I'm sitting here staring at this problem that says: f(x){2x+1, if x <1 f(x){-x+4, if x is greater than or equal to 1. Penny Nom lui répond.
	Piecewise functions		2006-09-24
		Claudia pose la question : hi! i was just looking at a question by someone else about piecewise functions, but i still don't get it. my problem is g(x){x+2 if x <-2} g(x){2x - 1 if x> or = -2} Penny Nom lui répond.
	Piecewise functions		2006-03-21
		Kris pose la question : First Problem: Southeast Electric charges .09 cents per kilowatt-hour for the first 200 kWh.The company charges .11 cents per kilowatt-hour for all electrical usage in excess of 200 kWh. How many kilowatt-hours were used if a monthly electric bill was $57.06? The answer I came up with is 360, is that right? and also how do I set it up in an equation form? Second Problem: A construction worker earned $17 per hour for the first 40 hr of work and $25.50 per hour for work in excess of 40 hr. One week she earned $896.75. How much overtime did she work? I came up with 8.5 hrs over-time worked. Again I don't know how to set up the equation to come up with the answer. I need some pointers on how to figure out story problems! If you have any suggestions that would help me out I would be very grateful. Penny Nom lui répond.
	f(x) = x-4 if x<2		2004-09-21
		Dani pose la question : Hi, my name is Dani. I'm in tenth grade Algebra 2, and I'm learning about a lot of different kinds of functions, and I can't quite seem to understand how every part of the piecewise function works. I understand most of it, I think, but I've been looking at an example in my math book, and I'm not sure how they got the answer they did. The part I don't understand reads: "Graph f(x) = x-4 if x<2" and "Identify the domain and range." The picture in the book shows an open circle at (2,-2), with an arrow going down and to the left with the slope being one. How did they get the open circle to be at (2,-2), and why does the arrow point where it does? Penny Nom lui répond.
