If f(x) = −4x 2 + 15, then f(−3)

-21

Step-by-step explanation:

f(-3) = -4(-3)² + 15 = -4(9) + 15 = -36 + 15 = -21

f(-3) = -21

Step-by-step explanation:

f(x) = −4x²+ 15

f(-3) = -4(-3)² + 15

f(-3) = -4(9) + 15

f(-3) = -36 + 15

f(-3) = -21

because they could drop even lower..

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above
