Which of the following represents the x-intercepts and the vertex of the quadratic relation y = −x2 − 6x + 27?
Question
Solution 1
The x-intercepts of the quadratic equation are found by setting y = 0 and solving for x.
So, we have:
0 = -x^2 - 6x + 27
This can be factored to:
0 = -(x - 3)^2 + 9
Setting each factor equal to zero gives the solutions x = 3.
The vertex of a parabola y = ax^2 + bx + c is given by the point (h Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
