Thank you for the opportunity to help you with your question!

(a) Estimate the value of f (5) by averaging.

to get it, you plugin 5 everywhere x is occurring and you solve the equation.

so if f=f(x) and x = 5 then f =f(5)

(43.7 +40.1)/2 = 41.9

(b) Find the average rate of change for f between x = 4 and x = 6.(No Response)

Rate of change = Difference between the two values / difference of values of x

=(43.7 +40.1)/ 6-4

=3.6/2

=1.8
