Mathematics for the International Student: Mathematics SL | 3rd Edition


Problem 15

A truck carrying a wide load needs to pass through the parabolic tunnel shown. The units are metres. The truck is \(5 \mathrm{~m}\) high and \(4 \mathrm{~m}\) wide. a) Find the quadratic function which describes the shape of the tunnel. b) Determine whether the truck will fit.

Accepted Solution
Step-by-Step Solution:

Step 1 of  2

a)  Consider the figure above,

The parabola cuts x-axis at -3 and 3.

We have conjugate (x-3) and (x+3)

Then ,

Parabola passes through (0,8)

So,

The quadratic function which describes the shape of tunnel is
