Given the function f(x) = log base 4(x+8) , find the value of f^-1(2)

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)
