Expert Solution
Step 1

a)To find the derivative of f(x) , we use the result that derivative of x^n is n*x^(n-1)

f(x) x-4x38
f(x) 4x3-12x2
Step 2

b)To find slope m of graph at x=-1 , we substitute x=-1 in f'(x)

f'(x) 4x3 -12x
m f(-) 4(-)-12(-1) -4-1=-16
Step 3

c)Now we find the value of y corresponding to x=-1

y ()4
8 = 1+4+8 13
