How to Understand Sign Diagrams – mathsathome
As we go past each axis intercept or asymptote on the sign diagram, we can see if the sign changes or not depending on the power of the factor that the value came from. As we move right past the asymptote at 𝑥 = 1, this asymptote came from the (𝑥 – 1) 2 on the denominator. 2 is even and so, we keep the sign the same.
