Question

If f(x) = x2 + x, find f(-3).

A. -12
B. 3
C. 6

Answer 1

I believe that this would be (-3)²+-3. A negative times a negative is always positive, so -3² would be 9-3. We don't need the + sign because we would still subtract three from 9, which gives you 6. The answer would be C.

Answer 2

C.

-3 squared is 9. 9 + (-3) is 6.

Therefore, it's C
