Since f(3)=1, this means that if we plug in x=3, we'll get f(x)=1.


Start with the given function.


Plug in


Plug in . Our goal is to now solve for C.


Cube 3 to get 27


Square 3 to get 9


Multiply


Combine like terms.


Subtract 177 from both sides.


Combine like terms.


So the value of C is making the function
