I’m confused with number 1? can you explain?

1. 15x + 3

Step-by-step explanation:

Given:

f(x) = 3x - 2

g(x) = 12x + 5

You are trying to solve:

f(x) + g(x)

Plug in the coresponding terms to the corresponding variables:

(3x - 2) + (12x + 5)

Combine like terms:

(3x + 12x) + (-2 + 5)

(15x) + (5 - 2)

15x + 3

15x + 3 is your answer.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

what is the original number? you forgot to add it.
