 $Find\ g\left(h\left(x\right)\right)\ for\ g\left(x\right)=2x-3\ and\ h\left(x\right)=3x+1$ 

 $s\left(x\right)=x\left(4-0.05x\right);\ \ e\left(x\right)=20+2x.$  Use the sales and expenses functions to find the revenue function.  Remember that 

revenue=sales-expenses.

 $Given\ f\left(x\right)=x+2\ and\ g\left(x\right)=x^2-2x+3,\ find\ \left(f\cdot g\right)\left(x\right).$
