`3x+2=5`


The number of ferryboat trips, `f(c)`, needed to transport c cars in 1 day can be found using the function `f(c) = c/20`. If there are no more than 5,000 cars transported by ferryboat daily, what is the range of the function for the situation?

Copy/paste the following into the formula window:


  • 3x+2=5
  • (2x-5)/5=1
  • sqrt(3x)/3=1
  • -b \pm \sqrt(b^2-4ac) / (2a)
  • f(a) = \frac{1}{2\pi i} \oint\frac{f(z)}{z-a}dz

Basic key:


  • + = plus
  • - = minus
  • / = divided by
  • ^ = power of
  • sqrt = square root
  • pi = pi
  • \sum = sum
