Question

Write a quadratic function with zeroes 6 and 7

Answer 1

f(x) = x² - 13x + 42

Explanation:

given zeros are x = 6 and x = 7 then the corresponding factors are

(x - 6) and (x - 7)

the quadratic function is then the product of the factors , that is

f(x) = (x - 6)(x - 7) ← expand using FOIL

= x² - 13x + 42
