The average percentage growth rate of function f[x] as x advances by one unit from x to x+1 is given by percent[x] = 100((f[x=1]/f[x]) - 1).
Use this formula to measure the average percent growth rate of f[x] = 3e0.7x as x advances by one unit.
Use this formula to measure the average percent growth rate of f[x] = 0.7x + 3 as x advances by one unit.
