Q. The equation of a parabola is y=x2+2x−7. 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.The vertex form of a parabola is given by y=a(x−h)2+k, where (h,k) is the vertex of the parabola.
Complete the square:Complete the square to transform the given equation into vertex form.The given equation is y=x2+2x−7. To complete the square, we need to add and subtract the square of half the coefficient of x inside the parentheses.The coefficient of x is 2, so half of it is 1, and squaring it gives us 1. We add and subtract 1 to complete the square.y=x2+2x+1−1−7
Rewrite equation: Rewrite the equation by grouping the perfect square trinomial and combining the constants.y=(x2+2x+1)−1−7y=(x+1)2−8Now, the equation is in vertex form, where (h,k)=(−1,−8).
