Question

HELP If you apply these changes to the linear parent function , f(x)-=x what is the equation of the new function vertically compress by a factor of 5 shift up 7 units

Answer 1

transformed function, g (x) = (1/5)(-x)+7

Explanation:

Assuming

f (x) = -x (and not f(x)-=x)

To compress/expand, we apply

g (x) = a*f(bx-k)+h

where

a=vertical stretch factor, a= 1/5 for compression (to stretch 5 times, a=5)

b=horizontal compression factor (=1 i this case)

h=vertical translation (=7)

k=horizontal translation (=0)

So the transformed function,

g (x) = (1/5)(-x)+7
