Question

Using the graph, determine the coordinates of the x-intercepts of the parabola.

Answer 1

the x intercepts are 1 and-5

Answer 2

x = -5, x = 1

As (x, y) coordinates, the x-intercepts are (-5, 0) and (1, 0).

Explanation:

The x-intercepts are the x-values of the points at which the curve crosses the x-axis, so when y = 0.

From inspection of the given graph, we can see that the parabola crosses the x-axis at x = -5 and x = 1.

Therefore, the x-intercepts of the parabola are:

• x = -5
• x = 1

As (x, y) coordinates, the x-intercepts are (-5, 0) and (1, 0).
