Which of the following is equivalent to the function f(x) = 2x² + 8 when the domain of f is x = 3

0, 10, 42

Step-by-step explanation:

f(x) = 2x² - 8

for x = -2

f(-2) = 2(-2)² - 8 = 2(4) - 8 = 8 - 8 = 0

for x = 3

f(3) = 2(3)² - 8 = 2(9) - 8 = 18 - 8 = 10

for x = 5

f(5) = 2(5)² - 8 = 2(25) - 8 = 50 - 8 = 42

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5 1/10

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
