Answer:
The graph is attached
- First identify the leading coefficient. It is positive in our case, it means the graph opens up
- Plot vertex,
- f(x) = a(x - h)² + k
- Vertex is (h, k), in our case it is (-5, -11)
- Find x and y-intercepts and plot
- To find x- intercepts find x when y = 0
- To find the y-intercept find y when x = 0
Once all points are plotted, connect them and extend up (see attached)
