Question
An equation that defines y as a function $f$ of $x$ is given. (a) Solve for y in terms of $x$, and write each equation using function notation $f(x) .(b)$ Find $f(3) .$ See Example $6 .$ $$ $y-3 x^{2}=2$
Step 1
We want to solve for $y$ in terms of $x$, so we need to isolate $y$ on one side of the equation. We can do this by adding $3x^{2}$ to both sides of the equation. This gives us $y = 2 + 3x^{2}$. Show more…
