Question

the choice highlighted was the wrong answer. the bottom 3 are the choice.

Answer 1

Answer:

Decreasing at a decreasing rate.

Explanation:

Given the function;

$y=-\sqrt[]{2x+5}$

Graphing the function to observe its behavior.

we have;

from the graph, we can observe that the value of y decreases as x increases.

Also, taking a close look at the graph, we can observe that the rate at which y decreases also decrease as x increases.

From x=0 to x=10, y decreases by approximately 3 units, while from x=10 to x=20 y decreases by approximately 2 units.

Therefore, y is decreasing at a decreasing rate.
