Question

ANSWER>> DETERMINE THE RANGE OF THE FUNCTION.

.
y = 1/4x^2 - 5
.
A) All real numbers.
B) All integers less than or equal to -5.
C) All integers greater than or equal to -5.
D) All real numbers greater than or equal to -5.

Answer 1

D

Explanation:

When the function or the coefficient in this case 1/4x^2 is positive it means it's opening up like a u, meaning all the values will be bigger than the C term or -5 in this case.

Answer 2

D

Explanation:

the function is open-up shape, and the vertex is (0,-5)

Because it opens up, the vertex is minimum value.

range is equal to or greater than -5
