Evaluating the Function f(x) = (1/2)^x for Given Values of x

In this article, we will evaluate the function f(x) = (1/2)^x for the given values of x and complete the table below. The function f(x) is an exponential function with base 1/2, and we will use this function to calculate the values of y for the given values of x.

The Function f(x) = (1/2)^x

The function f(x) = (1/2)^x is an exponential function with base 1/2. This function can be written in the form f(x) = a^x, where a is the base and x is the exponent. In this case, the base is 1/2.

Evaluating the Function for Given Values of x

To evaluate the function f(x) = (1/2)^x for the given values of x, we will substitute the values of x into the function and calculate the corresponding values of y.

Evaluating f(-3)

To evaluate f(-3), we will substitute x = -3 into the function f(x) = (1/2)^x.

f(-3) = (1/2)^(-3) = 1 / (1/2)^3 = 1 / (1/8) = 8

Therefore, f(-3) = 8.

Evaluating f(-2)

To evaluate f(-2), we will substitute x = -2 into the function f(x) = (1/2)^x.

f(-2) = (1/2)^(-2) = 1 / (1/2)^2 = 1 / (1/4) = 4

Therefore, f(-2) = 4.

Evaluating f(-1)

To evaluate f(-1), we will substitute x = -1 into the function f(x) = (1/2)^x.

f(-1) = (1/2)^(-1) = 1 / (1/2) = 2

Therefore, f(-1) = 2.
