Question

What is the value for ƒ(x) = 42x - 100 when x = 2 ?

Answer 1

-16

Explanation:

We are given that a function

`f(x)=42x-100`

We have to find the value of given function at x=2

To find the value of function at x=2 we will substitute x=2 in given function.

Substitute x=2 in given function

Then, we get

`f(2)=42(2)-100`

`f(2)=84-100`

Using multiplication property of integer

`f(2)=-16`

Subtraction property of integers

Hence, the value of function at x=2 =-16

Answer 2

f(2)=42(2)-100
f(2)=84-100
f(2)=-16
