Question: An exponential function has a base which is greater than 1, and the unknown or variable is the exponent. For example, 2x is an exponential

An exponential function has a base which is greater than 1, and the unknown or variable is the exponent. For example, 2x is an exponential function. When x is 0, 2x = 20 = 1. When x is 1, 2x = 21 = 2. When x is 2, 2x = 22 = 4. Now when x is negative, that means that the exponential function is 1/(x to the positive power). When x is -1, 2x = 2-1 = 1/21 = 1/2. When x is -2, 2x = 2-2 = 1/22 = 1/4. Evaluate 4x for the following values of x: 1) x = -2 2) x = -1 3) x = 0 4) x = 1 5) x = 2
