oh man u guys are super genioses

Try this one on for size:
H(x)=(x^2)+1 and K(x)=-(x^2)+4. If K(H)=0, what are the roots/solutions?

what does K(H) have to do with anything
is that meant to be functional composition or is that a typo

Lol, i'm learning 10th grade math as a 9th grader.

you're proud of that? lmao


find the derivative function of x^-2 algebraically using the limit of difference quotients (don't use the power rule >:( derive it)

d/dx(1/x^2) = -2/x^3
no clue what that means but wolfram alpha woo

K(H(x))=0? I think you may have messed up there...

K = 28
Basic 10th grade stuff brother

I learned this in pre-algrebra 2 years ago
I don't know what classes your taking
