College Precalc, just can't figure this out A large square carpet is initially x inches long and x inches wide. Randy decides to trim 4 inches off each edge of the carpet because the edges are... how can I show that x^5+4x^3-x^2=4x+1 has a solution using the IVT theorem?

how can I show that x^5+4x^3-x^2=4x+1 has a solution using the IVT theorem? find g(f(x)) when f(x)=8x-13 and g(x) = √x+9 and then the domain. (x+9 is in the quare root symbol not just x)

I need help with calculus homework. the √x+9 means that x+9 is all in the square root sign
