Answer:

Step-by-step 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:

Kindly check explanation

Step-by-step explanation:

Given the question :

Jane evaluates x squared minus 3 x + 5 for x = negative 2 below. Step 1: (negative 2) squared minus 3 (negative 2) + 5 Step 2: Equals negative 4 + 6 + 5 Step 3: Equals 7 What, if any, was Jane's mistake?

Jane's evaluation :

x² - 3x + 5 for x = - 2

Step 1:

(-2)² - 3(-2) + 5

Step 2:

-4 + 6 + 5

Step 3 :

= 7

Jane's mistake was in STEP2,

evaluating (-2)² = 4 and not - 4

Hence, (-2)² - 3(-2) + 5

= 4 + 6 + 5
