Question

Find the range of the graphed function.

A. Y is all real numbers

B. Y>_0

C. 0<_y<_10

D. -9<_y<_5

Btw, <_ or >_ is the greater than or equal to or less than or equal to sign.

Answer 1

The range of the function should be:

-9 ≤ y ≤ 5

Hence, option D is true.

Explanation:

We know that the set of values of the dependent variable for which a function is defined.

From the given function, we can easily observe that the graph is kind of oscillating between the y-value y = 5 and y = -9.

i.e.

at y = 5, the graph gets its maximum value

at y = -9, the graph gets its minimum value

Thus, the range of the function should be:

-9 ≤ y ≤ 5

Hence, option D is true.
