Quadratic Functions · Exercise 60

Use a calculator to find the answer.

A suspension bridge can be modeled by the quadratic function $h (x) = .0001 x^{2}$ with $- 2000 \leq x \leq 2000$ where $∣ x ∣$ is the number of feet from the center and $h (x)$ is height in feet. Use the TRACE feature of your calculator to estimate how far from the center does the bridge have a height of 100 feet.
