Question

Give the function f(x)=-2x-5 determine the value of f(-3)

Answer 1

We have the next function

`f(x)=-2x-5`

And we must calculate f (-3).

To calculate it we must replace x = -3 in the function.

`f(-3)=-2(-3)-5`

Finally, we must simplify the answer

`f(-3)=6-5=1`

So, the answer is

`f(-3)=1`
