What number should be added to both sides of the equation to complete this square? x^2-10x=7

What is the y intercept of f(x)=(1/2)^x?

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
