The correct answer is: 23

Explanation:

Given function:

f(x) = 3x^2 - 2x + 7 ---- (A)

f(-2) means that we have to put x = -2 in equation (A):

f(-2) = 3(-2)^2 - 2(-2) + 7 \\ f(-2) = 3*4 + 4 + 7 \\ f(-2) = 12+4+7 \\ f(-2) = 23 \\


Hence the correct answer is: f(-2) = 23.

Clara brought 24 donuts for the office. If 6 of them were chocolate, what percent of the donuts were chocolate
mafiozo [28]
To find the percent, you have to divide 24/6 
24/6 = 0.25
Now you convert 0.25 to a percent. 
So move the decimal point 2 places to the right. 
= 25 %
