(This problem is similar to the example in your textbook about guessing a formula for the derivative of f(x) = x² and to a similar problem in the exercises. Study that example carefully before doing this problem.) Let f(t) = 2t² +4t. Estimate the following to within two decimal places by using small enough intervals.(a.) f'(1) ?(b.) f'(-5) =(c.) f'(9) ?(d.) Determine a formula for f'(t). f'(t) =
