Write a quadratic function f whose zeros are -9 & -1

Mathematics
1 answer:
olganol [36]3 years ago
7 0

Step-by-step explanation:

This is most easily solved by writing the factored form:

f(x) = (x + 9)(x + 1)

Notice how, if we were to substitute -9 for x, the left part would be -9 + 9 = 0. Since (x + 1) × 0 = 0, this makes the function 0. The same logic applies for the right part.
