Question

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 7
- Shifts up 5 units.

A.
`g(x) = 7x + 5`
B.
`g(x) = (1)/(7) (x+5)`
C.
`g(x) = 7(x-5)`
D.
`g(x) = (1)/(7) x+5`

Answer 1

A, g(x) = 7x + 5

Explanation:

applying these translations to the parent function f(x) = x, we would get the following equation:

g(x) = 7x + 5

a vertical compression is written before the parent function (in this case f(x)=x), and a shift up is written next to the function. both of these are without parentheses

the answer would be A, g(x) = 7x + 5
