Question

Create a graph; then answer the following question.

What are the key points on the graph of y=x2−8x
? Name the vertex, x-intercept(s), and y-intercept.

(1 point)

Answer 1

y = x^2 − 8x is a parabola opening upward (a = 1).

Key points:
- Vertex: (4, −16)
- x-intercepts: (0, 0) and (8, 0)
- y-intercept: (0, 0) (same as one x-intercept)

Axis of symmetry: x = 4.
