A mountain road is 7 miles long and gains elevation at a constant rate. After 2 miles, the elevation is 5500 feet above sea level. After 4
miles, the elevation is 6200 feet above sea level.
Using the equation y=mx+b, determine what the elevation would be
after 5 miles?

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
