We are given the function below;

PART A
We then proceed to find if the function has a minimum or maximum value. To find if the function has a minimum or maximum value. If the x^2 coefficient is positive, the function has a minimum. If it is negative, the function has a maximum.
ANSWER: From the above, we can see that x^2 is negative, hence the function has a maximum
PART B and C
To find the minimum or maximum value, we would plot the graph of the f(x). The graph can be seen below.
From the graph, the black point helps answer part A and part B. 
ANSWER: The function's maximum value is f(x)=2. 
This is the point where the slope of the graph is equal to zero
ANSWER: The maximum value then occurs at x= -1
 We can also solve this by differentiating the function.

Answer:

Step-by-step explanation:
We are given this function for the height (h) after t seconds:

Seconds is t and we want to find the height after 1.5 seconds. Plug 1.5 in for t. 

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Solve the exponent first. 

Multiply. 


Add. 

This is already rounded to the nearest tenth, so it is the answer. 
After 1.5 seconds, the basketball is at a height of 7.5 feet.
