Suppose that f(x) is a function with f(115)=76 and f′(115)=4 Estimate f(117.5)

Haven't you beaten this type of problem to death yet? Surely by now you know how to solve them.

Using the definition of the derivative, we can estimate f(117.5) as follows:

f(117.5) ≈ f(115) + 4(117.5 - 115)
= 76 + 4(2.5)
= 84
