The x-intercepts of the parabola represented by y=x2−6x+8 in the xy-plane are the values of x for which y is equal to 0.The factored form of the equation, y=(x−2)(x−4),shows that y equals 0 if and only if x=2 or x=4. Thus, the factored form,y=(x−2)(x−4), displays the x−intercepts of the parabola as the constants 2 and 4. Choices A, B, and C are incorrect because none of these $$forms shows the x-intercepts 2 and 4 as constants or coefficients.
