The correct answer is the fourth choice
Functions have one output for every input. So that means one x-coordinate for one y-coordinate. In this case, (3,4) and (3,12) have the same x-coordinate, so it can't be a function.
Answer: That is a great question.
Step-by-step explanation:
Answer:
g(5) = 21
Step-by-step explanation:
Substituting f(x) into g(x):
g(x) = 2(3x-4) - 1
= 6x - 8 - 1
= 6x - 9
Seeing that g(x) = 6x-9,
g(5) = 6(5) - 9
= 30 - 9
= 21
