Question

Which ordered pair is not on the graph of h(x) =3x^2-5x+4

A) -3,46
B)-2,26
C)-1,12
D)-4,46

Answer 1

D

Explanation:

To determine the point that is not on the graph substitute the x- coordinate into h(x) and if the value obtained is equal to the y- coordinate of the point then it lies on the graph

h(- 3) = 3(- 3)² - 5(- 3) + 4 = 27 + 15 + 4 = 46

(- 3, 46) ← lies on the graph

h(- 2) = 3(- 2)² - 5(- 2) + 4 = 12 + 10 + 4 = 26

(- 2, 26)← lies on the graph

h(- 1) = 3(- 1)² - 5(- 1) + 4 = 3 + 5 + 4 = 12

(- 1, 12) ← lies on the graph

h(- 4) = 3(- 4)² - 5(- 4) + 4 = 48 + 20 + 4 = 72 ≠ 46

(- 4, 46) ← does not lie on the graph

Answer 2

The ordered pair that is not on the graph is (-4,46)
