The function r(x) = –0.000345(x – 50)2 + 2.1 can be used to model the curve of a road designed to allow for water to run off in rainstorms depending on the distance from the shoulder of the road, x, in feet. A European firm studying these curves is going to convert feet to meters using the function m(x) = 0.3048x. Which composition can be used to model the curve of the road in terms of meters? m(r(x)) = –0.000105156(x – 50)2 + 2.1 m(r(x)) = –0.000105156(x – 50)2 + 0.64008 m(r(x)) = –0.000345(0.3048x – 50)2 + 2.1 m(r(x)) = –0.000345(0.3048x – 50)2 + 0.64008

Step-by-step explanation:

Composite Function

The composition of functions f(x) and g(x) is denoted as and can be obtained by the expression

In practice, it means to replace into each x of f, the whole expression for g.

We know the function

can be used to model some reality, being x in feet. We also know that another function

is going to be used to convert feet to meters. We are required to find

We'll replace the expression for r into m as:

Operating

where did you get them? if you picked from the grass, is is probably poisonous.
