Question Write the equation $y = -3x + 9$ in function notation as $f(x)$ .

Studdy Solution

STEP 1

Assumptions1. The given equation is $y=-3x+9$ . We need to express this equation in function notation using $f(x)$

STEP 2

In function notation, $f(x)$ is used to represent the output of the function for an input $x$ . In this case, $y$ is the output of the function for an input $x$ . So, we can replace $y$ with $f(x)$ in the given equation.
$f(x) = -x +9$ This is the given equation in function notation.
