SOLUTION: These are the only 2 I'm having problems with. I know how to solve them when f(x)= a number. But how do i solve it when there is a number = a number?
If f(x) = 3x3 + 9x2 - x

Question 332792: These are the only 2 I'm having problems with. I know how to solve them when f(x)= a number. But how do i solve it when there is a number = a number?
If f(x) = 3x3 + 9x2 - x + C and f(3) = 1, what is the value of C?
If f(x) = (x-5A)/(-10x+2) and f(-10) = -15, what is the value of A?
Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!
\ =\ 3x^3\ +\ 9x^2\ -\ x\ +\ C)
\ =\ 1)
\ =\ 3(3)^3\ +\ 9(3)^2\ -\ (3)\ +\ C\ =\ 1)
\ =\ 81\ +\ 81\ -\ 3\ +\ C\ =\ 1)
So just solve
Work the other one the same way.
