answer the question correctly to continue:
over a certain interval, a functions graph goes from 40 to 20. what does this indicate?
the graph is increasing.
the function is decreasing over that
the graph is constant.
the domain is increasing.

Explanation:

Step1: Analyze function behavior

If a function's value goes from 40 to 20 over an interval, it means the output \(y\) - values are getting smaller.

Step2: Recall function trends

A function is increasing when \(y\) - values rise as \(x\) increases (\(y_2>y_1\) for \(x_2 > x_1\)), decreasing when \(y\) - values fall as \(x\) increases (\(y_2 x_1\)), and constant when \(y\) - values stay the same. Here, since \(20<40\), the function is decreasing.

Answer:

The function is decreasing over that interval.
