Question

Given the function g(x) = 4x − 5, find g(−3).

Answer 1

just substitute (-3) for the x on g(x) function

Answer 2

Since it's given you what g is equal to in parentheses, you can infer that the equation you see there you have to plug in -3. That's because it's telling you what g(x) stands for. I hope you understand it now, so that if a similar question ever comes up, you can totally figure it out now! :)

Answer 3

Just replace all the x's with -3
