I was given $R(x)=-1.5x^2+250x$ which represents the game systems sold and $C(x)=80x+150$ representing the cost to produce them. The restriction for $R(x)$ is $0 \leq x \leq 166$ and the restriction for $C(x)$ is $x \geq 0$.
I was also given the the equation for the profit which was $P(x)=R(x)-C(x)$, and the answer that I got was $P(x)=-1.5x^2+170x-150$.
Now I have to graph $y=P(x)$. I would just appreciate some suggestions on how to approach this or where to begin and what to find.
