**Solve Problem**

1. John owns a hot dog stand. He has found his profit is given by the equation P=-x^2+68x+79, where x is the number of hot dogs sold. How many hot dogs must he sell to earn the most profit?

**Find the requested value**

2. F(5) for f(x)= {4x+4 if x ≤ 0

{4-4x if 0<x<4

{ x if x ≥4

**Solve the problem**

3) The gravitational attraction A between two masses varies inversely as the square of the distance between them. The force attraction is 2.25lb when the masses are 4 ft apart, what is the attraction when the masses are 6ft apart?

**Evaluate**

4) If f(x) = 3x-3 and g(x)=4x^2+14x+3, evaluate (f/g)(-5)

**Find the requested composition of function**

5) Given f(x)=4x^2+3x+6 and g(x)=3x-8, find (g ° f)(x).
