Answer:
f(x) = x² + 10x + 21
Step-by-step explanation:
- Let the zeroes be r and s respectively
- r = -3 and; s = -7
Quadratic Functions are always in the form of:
f(x) = ax² + bx + c
- Since the roots are already given, we can just move backwards.
x = -3
x + 3 = 0
x = -7
x + 7 = 0
(x + 3)(x + 7) = 0
f(x) = x² + 10x + 21
Therefore, the Quadratic Function is :
f(x) = x² + 10x + 21
