Question

problems 9 - 10: spiral review
here is the function ( h(x) ).
write the coordinates of this functions minimum.
write an interval that describes where the graph is decreasing.

Explanation:

Step1: Identify the minimum point

The minimum of a function on a graph is the lowest point. Looking at the graph, the lowest \( y - \) value occurs at \( x = 15 \) and \( y=-5 \). So the coordinates of the minimum are \( (15,-5) \).

Step2: Determine the decreasing interval

A function is decreasing when, as \( x \) increases, \( y \) decreases. From the graph, we can see that the function is decreasing from \( x = 0 \) to \( x = 15 \).

Answer:

Coordinates of the minimum: \( (15,-5) \)
Interval where the graph is decreasing: \( 0\leq x\leq15 \)
