Chapter 8, Problem 4CR

To determine

To write:

The given equation using function notation.

Answer to Problem 4CR

The given equation in function notation would be $f(x)=-5x+2$ .

Explanation of Solution

Given:

An equation:

  $y=-5x+2$ .

Concepts used:

To write an equation in function form, we need to replace y with $f(x)$ , where $f(x)$f as a function of x.

Calculation:

Upon replacing y with $f(x)$ in our given equation, we will get:

  $\begin{array}{l}y=-5x+2\left(\text{Given equation}\right)\\ f(x)=-5x+2\left(\text{Replacing }y\text{with }f(x)\right)\end{array}$

Therefore, the given equation in function notation would be $f(x)=-5x+2$ .
