Step-by-step explanation:
Given function 
is linear function. This linear function represents the straight line on the coordinate plane. The slope of this line is 
Since the slope is negative, the linear function is decreasing for all x. This means
You ar geven the interval 
So, the maximum value of the function is at the point x=-4 and the minimum value of the function is at the point x=3.
At x=-4,
Answer:
45
