Question

y=x^2-9
(a) sketch a graph of the equation
(b) identify the vertex
(c) compare the graph of y=f(x) to the graph of y=X^2

Answer 1

The vertex is (0, -9). The graph is translated down 9 units from the parent function y = x^2

Answer 2

the sketch shows that it is left 3 and right 3 correct

Answer 3

There are x-intercepts at 3 and -3.
