Algebra II: Identifying Quadratic Equation from Points

Since the axis of symmetry is x = 1 and one x-intercept is (3, 0), then the other x-intercept must be (-1 , 0) (to maintain symmetry) Step 1 : Write general formula of quadratic y = a(x — p)(x — q) where p and q are the x- intercepts Step 2: Substitute given values (to determine "a") Step 3: Write equation of the quadratic (x + l)(x — 3) ................
