Solve for x: log 10^x = 21

The difference of 2 numbers is 21 and the quotient of the equation is 4 then what are the two numbers?

Look at the following graph of the given equation. determine whether the equation is a function. explain why or why not.

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
