Question:

A regular region of length {eq}x {/eq} and width {eq}y {/eq} has an area of 493 square meters. Write the width {eq}y {/eq} as a function of {eq}x {/eq}.

Rectangle:

Consider a rectangle of dimensions {eq}l \times b {/eq}

It's area is given by {eq}A = lb {/eq}

It's perimeter is given by {eq}P = 2(l+b) {/eq}

Answer and Explanation:

Given area:

{eq}xy = 493 \\ y = \frac{493}{x} = f(x) {/eq}

Hence y is written as a function of x
