Answer:
Explanation:
The given function is
f(x) = x^2 - 2x - 3
The first step is to graph the function. We would substitute values of x into the function and find corresponding values of y or f(x). We have
For x = - 1, y = (- 1)^2 - 2(- 1) - 3 = 1 + 2 - 3 = 0
For x = 0, y = (0)^2 - 2(0) - 3 = 0 + 0 - 3 = - 3
For x = 1, y = (1)^2 - 2(1) - 3 = 1 - 2 - 3 = - 4
The points to be plottted on the ggraph are
(- 1, 0)
(0, - 3)
(1, - 4)
We would plot these point on the graph as shown below
The axis of symmetry is the vertical line that divides the graph into two equal hv
