Problem 71 of 7
Graph the quadratic function y=x(x-4) from intercept form. State zeros and axis or vertex.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
plot zeros and locate axis/vertex.
Hidden until you reveal it.
Function must be factored with visible zeros and graphable vertex.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Set each factor equal to zero to find x-intercepts.
2. The axis of symmetry is halfway between zeros when two zeros are present.
3. Evaluate the function at the axis to find the vertex.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using factors as y-intercepts.
