    6. Prove that f(x) = (3/4)x^4 + 2 and g(x) = (4sqrt(108x-216))/3 are inverses. I know you solve it with composite functions f(g(x)) and g(f(x)), and I solved f(g(x)), but I can't seem to solve g(f(x)) to equal x, like it should. Can someone show me how to

    How do you us implicit differentiation to solve x( y + 2 )^5 = 8 x( y + 2 )^5 = 8 ( y + 2 )^5 d/dx (x) + x d/dx(y+2)^5=d/dx 8 (y+2)^5 + 5x(y+2)^4 dy/dx=0 solve for dx/dy (Broken Link Removed) I assume you want dy/dx. Differentiate both sides of the

    Explain two ways that you can solve for R in the following division statement. Then, use one of your methods to find R. x^3+4x^2-3x=(x-1)(x^2+5x+2)+R could you divide x^3+4x^2-3x by (x-1) to get the quotion of (x^2+5x+2)+ the remainder which would be r?
