Could you please help with these three math pages.

Simply 8x squared + 5(7x squared- x) - 2x =

Is appreciated! graph the functions and approximate an x-value in which the exponential function surpasses the polynomial function. f(x) = 4^xg(x) = 4x^2options: x = -1x = 0x = 1x = 2

If f(x)= sqrt4x+9+2, which inequality can be used to find the domain of f(x)?
