All of the following statements are true about solving exponention inequalities, except?

• If b > 1, then the exponential function y = b^x id increasing for all x. This means that b^x < b^y if anf only if x< y

• If 0<b<y, then the function y = b^x is decreasing for all x. This means thay b^x > b^y if and only if x < y

• If the base is greater than 1, the direction of the inequality is retained

• If the base is less than 1, then the direction of the inequality is retained.
