Homework Help: math

Posted by John on Sunday, September 21, 2008 at 6:35pm.

sketch the image of f(x) after:

a) a horizontal compression by a factor of 1/2
b) a veritcal expansion by a factor of 3
c) both transformations in parts a and c have been applied

d) write the equations of the three image for a b and c

i think i graphed a b and c right
but i cant seem to get the equations

i thought it was:
a) y = f(2x)
b) y = f(x-3)
c) y = f(2(x-3))

but the back of the book says
a)f(x) = (root(4-(2x-2)squared)
b) f(x) = (3(root(4-(x-2)squared)))
c) f(x) = (3(root(4-(2x-2)squared)))
