Question

how would i solve this?

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

Answer 1

just replace for x=-3
g(-3)=4*(-3)-5

Answer 2

Where ever there is an x put -3 in its place. Like so

g(x) = 4(-3) - 5
Now solve for g(x)
g(x) = -12 - 5

I will let you finish

Answer 3

-17 but the guy above you subsituted x by g whichyou didnt

Answer 4

He put -3 in g(x) is that what you are talking about? where he g(-3) ?

Answer 5

yea

Answer 6

That is the correct form. You do not have to do that but that is for showing that x is an input. g(x) is a function and functions take input and you show the input by g(-3), which he is saying, he is inputing -3 for x or x = -3
