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
