Question

Evaluate the function at the given value and simplify.

f(x)=−5x+1

, f(−2)

Question 4 options:

a)

-9

b)

11

c)

-11

d)

9

e)

none

Answer 1

The correct option is b.

Explanation:

The given function is

`f(x)=-5x+1`

We need to find the value of f(-2). It means we have to find the value of given function at x=-2.

Substitute x=-2 in the given function to find the value of f(-2).

`f(-2)=-5(-2)+1`

On simplification we get

`f(-2)=10+1`

`f(-2)=11`

The value of f(-2) is 11. Therefore the correct option is b.
