How do you find the vertex and axis of symmetry, and then graph the parabola given by: #y = x^2 - 4x + 1#?
Standard form is:
your equations is already in standard form.
The formula for the axis of symmetry is:
Formula for the vertex point
what is f(aos)? that means you put the value you found for the aos back into the function as x and solve for y:
so the vertex is:
Finally to help you graph the y-intercept is
y-int = 1
also the x-intercepts are the roots if you factor the polynomial, you would need to use the quadratic formula to factor this one and the roots will be:
