Answer:
a) Vertex is at (-3, -1)
b) y-intercept is at (0,8)
c) x intercept is at (-4,0) and (-2,0)
d) x=-3
Step-by-step explanation:
The vertex of a parabola is the lowest or highest point, implying that all points are reflected across it. It's the only y value that doesn't have a corresponding pair.
For example, -1 and 1, -3 and 3, and so on.
The vertex is at (-3,-1) because it is the sole point without a corresponding y value (-3,-1)
The y-intercept is where the parabola meets the y axis or when the x value equals 0. To determine the y-intercept, simply find when x = 0.
intercept y: (0,8)
The x-intercepts are the same as the y-intercepts; you must determine where the parabola crosses the x-axis or when y = 0.
x intercept 1:(-4,0)
x intercept 2: (-2,0)
The axis of symmetry is also the x coordinate of the vertex which is 3 so
x = 3
