Logarithms/Exponentials 2u question (answered)

Im not sure if i'm overthinking for this question but i've been trying to solve simultaneously and idk where to go from there, do we just have to sub in x=-1 into both equations and prove they both give the same answer hence they intersect at x=-1?????

Show that the curves y=x^2 and y=e^(x+1) intersect at x=-1

Help is appreciated!!

Yeah, at a time like that all you can do is sub in \(x=-1\) and verify you get the same \(y\) value both ways.

There is no way to solve \(x^2 = e^{x+1} \) using elementary methods
