Answer: B, D, and E
<u>Step-by-step explanation:</u>
f(x) = x² - 1
(0, 1): 1 = (0)² - 1 ⇒ 1 = -1 FALSE
(1, 0): 0 = (1)² - 1 ⇒ 0 = 0 TRUE
(3, 5): 5 = (3)² - 1 ⇒ 5 = 8 FALSE
(5, 24): 24 = (5)² - 1 ⇒ 24 = 24 TRUE
(-2, 3): 3 = (-2)² - 1 ⇒ 3 = 3 TRUE
(-4, -17): -17 = (-4)² - 1 ⇒ -17 = 15 FALSE
That would be 7 because 7x2=14 and 14-9=5
The price of each taco is $10.5
