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)
