Using the given function below, determine if the following coordinate points area solution to the function
y = 3x2 + 1
(1,5) (-2,13)

see explanation

Step-by-step explanation:

To determine if the points are a solution substitute the x- coordinate into the function and if the value obtained is equal to the y- coordinate of the point then it is a solution

(1, 5)

y = 3(1)² + 1 = 3 × 1 + 1 = 3 + 1 = 4 ≠ 5 ← (1, 5) is not a solution

(- 2, 13)

y = 3(- 2)² + 1 = 3 × 4 + 1 = 12 + 1 = 13 ⇒ (- 2, 13) is a solution

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.

ik how do do this just give me a few minutes and i will give it to
