The x-intercept of a graph is the point where the graph crosses the x-axis

(a) Graph

The function is given as:

[tex]y = (x + 4)^2 - 7[/tex]

See attachment for the graph of the function.

From the attachment, the approximated x-intercepts are -7 and -1

(b) Type of solution

From the attached graph, we can see that the curve crosses the x-axis at non-terminating decimals

Hence, the solutions of the equation are irrational.

(c) The vertex

This is the minimum or the maximum point of a parabola.

From the attached graph, the minimum point is at (-4,-7)

Hence, the coordinates of the vertex of the parabola is (-4,-7), and it is exact (not approximated)
