Question

Given , find f(7).
–4
3
7
56

Answer 1

Explanation:

the answer to this would be A

since you do 10-2(7)=-4

Answer 2

we have

`f(x)=10-2x`

we know that

`f(7)` ----> is the value of the function for
`x=7`

so

substitute the value of x in the function

`f(7)=10-2*7=-4`

therefore

the answer is

`f(7)=-4`
