{(-12, 3) (-5,4) (-6,3)
(8.-9) (-6,2) (1,7)

is it a non function or a function?

No

Step-by-step explanation:

These points would not be a function as one x value shares more than one y value. The -6 shares both 2 and 3 as a y value.

In order to have a function, and x value can only have one y value. However, a y value can correspond to multiple x values and it can still be a function.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
