They both get 2 and 1/2 of a cookie!
First replace the letters with the numbers it gave so you have 3(2)(7)^2-(2)^2
multiply the 3 and 2 together to make 6(7)^2-(2)^2
do seven to the second power (7x7) so you get 6(49)-(2)^2
-(2)^2 is the same as -1(2)^2, so that can just become -2^2. so you now have 6(49)-2^2
multiply 6x49 so you have 294-2^2
do two to the second power (2x2) so you get 294-4
294-4=290
The value of f(3) would be 6.
Using our formula, we know that f(1) = 10, and f(2) = f(1) - 2 = 10-2 = 8. That means that f(3) = f(2) - 2 = 8 - 2 = 6.
Hmmmmm... I don’t really know I’m so sorry I couldn’t help :(( good luck though!
The answer to this question is:
83/100
