question 6
Use the vertex and intercepts to sketch the graph of the quadratic function. Give the equation of the​ parabola's axis of symmetry. Use the graph to determine the domain and range of the function.
f left parenthesis x right parenthesis equals 4 x minus x squared minus 3
Use the graphing tool to graph the equation. Use the vertex and one of the intercepts to draw the graph.

The axis of symmetry is
nothing.
​(Type an​ equation.)

The domain of the function is
nothing.

The range of the function is
nothing.
