The graph of f(x)=x2−2x−3 is shown above. a) Determine the x-intercepts of the graph. (Note: List the value(s) of x separated by a comma.) b) Find the solution(s) for: x2−2x−3=0

The graph opened upwards with a vertex on (1,-4). Not sure if this is needed but included it since the graph image was too large to include with this description.
