Question

6.) Consider the functions f(x) = -2x + 1 and g(x) = 4x - 5

find f(3)

Answer 1

`f(3)=-5`

Explanation:

We have the functions
`f(x)=-2x+1` and
`g(x)=4x-5`

We want to find
`f(3)`. So, we can use our first function.

Substitute 3 for x. This yields:

`f(3)=-2(3)+1`

Multiply:

`f(3)=-6+1`

Add:

`f(3)=-5`

So:

`f(3)=-5`
