Question

write a quadratic function f whose zeros are 7 and -2

Answer 1

Hello Brandy,

The quadratic function would be: f(x) = a* (x- zero1)*(x-zero2) where a can be any integer not equal to zero. To make it simple, you can let a = 1

You're told the zeros are 7 and -2 so f(x) = (x-7)(x- -2) = (x-7) (x+2) = x² +2x - 7x - 14 = x² - 5x - 14

Happy New Year.
