F(x) = x2 - 5
For the function shown, what is the range of the function when the domain is {2, 4, 7}?
A) {-1, 44}
B) {-1, -5}
C) {6, 21, 54}
D) {-1, 11, 44}

D

Step-by-step explanation:

Given that f(x) has domain { 2, 4, 7 }

Substitute the values from the domain into f(x) for the range

f(2) = 2² - 5 = 4 - 5 = - 1

f(4) = 4² - 5 = 16 - 5 = 11

f(7) = 7² - 5 = 49 - 5 = 44

Thus the range is { - 1, 11, 44 } → D
