The correct answers are option B x-intercepts: (–4, 0), (2, 0) and option C  Vertex: (-1,-9).
What is coordinate geometry?
A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y
.x-intercept(s): (−4, 0)(2,0)y-intercept(s): (0,−8)
When we plot the graph of the function we will get the vertex point of the parabola generated on the x and the y axis.
The graph of the function is also attached with the answer.
