Question

Write a quadratic function f whose zeros are 2 and 7.

Answer 1

f(x) = (x - 2)(x - 7)

Explanation:

an easy way to write a quadratic function who has zeroes of certain numbers is to use this format- f(x) = a(x - p)(x - q)

in this format

the p and the q are both zeroes

it does not matter what the a value is

an example for when the zeroes are 2 and 7 could be

f(x) = (x - 2)(x - 7)
