6 balls in the bag
1/6 getting the random color
1/6=about .16
so C
F(x)=3x^2-5 when x=-11
f(-11)=3(-11)^2-5
f(-11)=-33^2-5
f(-11)=1089-5
f(-11)= 1084
Hope this could help!

This is an exact answer. the answer will be a bit larger than 20
Your answer is no solution (because a negative square root doesn't exist)
first, you divide all sides by five and then take b, half it then square it
