Answer:

Step-by-step explanation:
From the question we are told that:
Function given

Co-ordinates
(x,y)=[1, 4]
Generally the second differentiation of function is mathematically given by

Therefore critical point

Generally the substitutions of co-ordinate into function is mathematically given by
For 1

For 4

For critical point 3

Therefore the maximum value of f(x) = –x2 + 6x over the interval [1, 4] is given by

Convert 97.5 inches to centimeters. 97.5 in=247.65 cm. The area is 247.65 inches^2. Hope this helps! ;)
The exponent in the equation is the 5.
