Q. The equation of a parabola is y=x2−8x+19. Write the equation in vertex form.Write any numbers as integers or simplified proper or improper fractions.______
Identify vertex form: Identify the vertex form of a parabola, which is y=a(x−h)2+k.
Start with given equation: Start with the given equation y=x2−8x+19.
Complete the square:Complete the square by adding and subtracting (8/2)2, which is 16, to the equation.y=x2−8x+16+19−16
Rewrite equation: Rewrite the equation grouping the perfect square trinomial and combining the constants.y=(x2−8x+16)+19−16y=(x−4)2+3
