F(x) = 6x + 3
g(x) = 3x - 2

B

Step-by-step explanation:

this is really not complicated.

the input value is the value of x.

so, just put that value into the equations and simply calculate.

f(2) = 6×2 + 3 = 15

g(-9) = 3×-9 - 2 = -29

15 + -29 = 15 - 29 = -14

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
