Finding a Quadratic Equation with the x-intercepts and Another Point
Finding a Quadratic Equation with the x-intercepts and Another Point Since we know the x-intercepts Find a rule for the quadratic table below. Sketch: Substitute into Factored Form: Plot all the points The “a” is the GCF Plug in the x-intercepts Use symmetry to find any missing x-intercepts (-1,0) (3,0) Plug in another point Solve for a Equation:
Finding a Quadratic Equation with the x-intercepts and Another Point Find a rule for the quadratic table below. Since we know the x-intercepts Substitute into Factored Form: There may be a GCF (adjustment value) Plug in the x-intercepts We need to solve for “a” but there are 3 variables Plug in another point Solve for a Equation:
