Question
use the drawing tool(s) to form the correct answers on the provided graph. consider the given function. $h(x) = (x + 1)^2 - 4$ plot the x-intercept(s), y-intercept, vertex, and axis of symmetry of the function. drawing tools select mark feature line click on a tool to begin drawing
Step1: Identify vertex from vertex form
The function is in vertex form $h(x) = (x-h)^2 + k$, where $(h,k)$ is the vertex. Here $h=-1$, $k=-4$, so vertex is $(-1, -4)$.
Step2: Find axis of symmetry
Axis of symmetry is $x=h$, so $x=-1$.
Step3: Calculate x-intercepts (set $h(x)=0$)
$$(x+1)^2 - 4 = 0$$
$$(x+1)^2 = 4$$
$$x+1 = \pm 2$$
$x+1=2 \implies x=1$; $x+1=-2 \implies x=-3$.
So x-intercepts are $(1,0)$ and $(-3,0)$.
Step4: Calculate y-intercept (set $x=0$)
$$h(0) = (0+1)^2 - 4 = 1 - 4 = -3$$
So y-intercept is $(0, -3)$.
