If f(x) = 1/3x^2 + 5, find f(-9).<br> A. 248<br> B. -22<br> C. 11<br> D. 32
melamori03 [73]

Answer:

D. 32

Step-by-step explanation:

For this problem, we simply plug -9 in for x in f(x):

f(x)=\frac{1}{3} x^2+5  ⇒  f(9)=\frac{1}{3} *(9^2)+5=\frac{1}{3} *81+5=27+5=32

Thus, the answer is D. 32.

Hope this helps!
