ANSWER
See below
EXPLANATION
Part a)
The given function is

From the graph, we can observe that, the absolute maximum occurs at (-0.7746,6.1859) and the absolute minimum occurs at (0.7746,5.8141).
b) Using calculus, we find the first derivative of the given function.

At turning point f'(x)=0.

This implies that,



We plug this values into the original function to obtain the y-values of the turning points

We now use the second derivative test to determine the absolute maximum minimum on the interval [-1,1]


Hence

is a maximum point.

Hence

is a minimum point.

Hence (0,-6) is a point of inflexion
A constant can either shift the graph up or down. If coefficient is less than 1 it will make the graph wider, if it's more than 1 it will make graph more narrow
