Question
Graph each parabola by hand, and check using a graphing calculator. Give the vertex, axis, domain,and range.$$x=(y+1)^{2}$$
Step 1
The vertex form of a parabola is $x=a(y-h)^2+k$, where $(k,h)$ is the vertex. In the given equation, $x=(y+1)^2$, we can see that $k=0$ and $h=-1$. So, the vertex of the parabola is $(0,-1)$. Show more…
