Question

vWhich graph can be used to find the solution(s) to x2 – 1 = 3?

Answer 1

the x-coordinate of the intersection point of the lines y = 3x + 5 and y = 2x – 7
the x-coordinates of the x-intercepts of the lines y = 3x + 5 and y = 2x – 7
the y-coordinate of the intersection point of the lines y = 3x + 5 and y = 2x – 7
the y-coordinates of the y-intercepts of the lines y = 3x + 5 and y = 2x – 7

Answer 2

always be successful, the Quadratic Formula can always find the solution. ... Since there were two solutions for x2 + 3x – 4 = 0, there must then be two x-intercepts on the graph.
