Question 182030This question is from textbook College Algebra The Graphing Approach
: This is a two part question:
The function f(x) is graphed points are (3,-1), (1,0), (0,3), (-2,4)
Graph y=-f(x-2)
I'm not sure but I have the new points as (-3,-1), (0,1), (0,3) (2,4)
Could you check this for me
The funtion f(x) is graphed points are (3,-1), (1,0), (0,3), (-2,4)
Graph y=f(2x)
I have a TI-84 Plus - I'm not sure how to use it very well and my instructor doesn't give much in the way of using it. So I'm kind of lost.
Thanks for your help

You can put this solution on YOUR website! Points are of form:
(x,y) or (x, f(x))
f(x-2) tells you to subtract 2 from each x to get new y, but you need to add 2 to undo this. So add 2 to each x (keep y the same)
New points:
(5,-1), (3,0), (2,3), (0,4)
-------------------------------------------------
f(2x) tells you to double each x. Need to take half of each x to undo this
New points:
(1.5, -1), (0.5, 0), (0, 3), (-1, 4)
