Question

Can someone help me with this please

Answer 1

Answer:

Step-by-step explanation:

The wording on this is not the best.  It sounds like the 1 zero has even multiplicity (that's because of where the modifier is). On top of that it has an odd power.  You could try this. y =x*(x^2+1)^2

The problem is not with the power. It gives x^5. The problem is with the multiplicity of the one place where it crosses. (X^2 + 1) does factor, but it gives a complex root. I'm not sure that's allowed. However, it is the best I can do.
