Compare the functions y = 2x2 and y = 2x. which of the following statements are true? check all that apply. for any x-value, the y-value of the exponential function is always greater. for any x-value, the y-value of the exponential function is always smaller. for some x-values, the y-value of the exponential function is smaller. for some x-values, the y-value of the exponential function is greater. for any x-value greater than 7, the y-value of the exponential function is greater. for equal intervals, the y-values of both functions have a common ratio.
