Range:
Explanation of Solution
Given information:
The height(in feet) of a softballt seconds after it is pitchedis given by the function:
Concept Used:
Maximum and Minimum value:
The y -coordinate of the vertex of the graph of
Vertex
And
Calculation:
Comparing the given function
First find the vertex
So, the vertex is
Since, here
So, the maximum height of the softball is the y -coordinate of the vertex that is, maximum height is 18 feet.
The graph of the given function is:
Domain of the given function is the time from when the ball is pitched to the time it hits the ground.
By observing the graph it can be said that:
Domain:
Range:
