Question

select the correct answer.
what is the range of this function?
a. $4 \leq y < \infty$
b. $-1 \leq y < \infty$
c. $\infty < y \leq -1$
d. $\infty < y \leq 4$

Explanation:

Step1: Identify the function's peak

The graph has a maximum y-value of 4 at its highest point.

Step2: Identify the function's lower values

The graph extends downward infinitely (towards $-\infty$) with no minimum y-value.

Step3: Define the range

The range includes all y-values from negative infinity up to and including 4.

Answer:

D. $-\infty < y \leq 4$
