Warm-up

The graph of the function $y=\dfrac{1}{x^2}$ is stretched as shown in this diagram.

If the graph is stretched by a factor of $b$ in the $x$-direction (as shown), what is the equation of the resulting graph?

And if, instead, the original graph is stretched by a factor of $c$ in the $y$-direction, what is the equation of the resulting graph?
