Question

If g (x) = 3x -8 find g(-1)

Answer 1

plug in -1 in place of x :)

Answer 2

g(-1) just means evaluating the function at said value.
as an example.
f(x)=3x-8, evaluated at f(0) means
f(0)=3(0)-8=-8.
Now the same applies to your case.

Answer 3

So g (-1) = 3 (-1) -8 ?

Answer 4

Exactly!

Answer 5

What's the next step to follow?

Answer 6

What is 3* -1 = ?

and then you subtract 8 from it and that's all :)
