help please?
Which graph can be used to find the solution(s) to x2 – 1 = x + 1?




Answer:
Option 3rd is correct.
Step-by-step explanation:
We have been given an equation:
[tex]x^2-1=x+1[/tex]
We can see that the graphical method gives the solution by intersection of two graphs.
So, one graph is of parabola open upwards
And the right hand side is the straight line.
Option 1 and 2 are discarded being open downwards.
And Option 3rd is correct.
Intersecting at (-1,0) and (2,3).
