Question
An equation that defines y as a function of $x$ is given. (a) Rewrite each equation using function notation $f(x) .$ (b) Find $f(3) .$ See Example $8 .$$$x+3 y=12$$
Step 1
To do this, we subtract $x$ from both sides of the equation to isolate $3y$ on one side. This gives us $3y = -x + 12$. Show more…
