Question

Given f(x) = x – 10, what is f(–7)?

A.
–17

B.
–10

C.
–7

D.
–3

Answer 1

easy
put -7 for every x
f(x)=x-10
f(-7)=-7-10
f(-7)=-17

A

Answer 2

Answer: A. $-17$

Step-by-step explanation:

Here,  the given function is,

$f(x) = - x - 10$

By substituting x = -7

We get,

$f(-7) = -7 - 10$

$\implies f(-7) = - (7+10)$

$\implies f(-7) = -17$

Thus, the value of $f(-7)$  is  $17$.

⇒ Option A is correct.
