Question: suppose f is a quadratic function that has roots at...

Question details

suppose f is a quadratic function that has roots at z = -5 and z = 8, and f(0) = 17, we will write a function formula for f. a. Sketch a graph of f based on the information you are given. b. We can write f as f(z) c . (z-z)(z-z2) where zi < z2 and c is some constant number. What are the values of zi and z2? Preview Preview c. Replace zi and z2 in the formula f(z) -c.(x -zi)(x -z2) with the values you found above. Use the fact that f(0) 17 to determine the value of c. Preview d. Write a function formula for f (in terms only z). f(x) = Preview
