sammy [17]

The value of function on x=1 is 0.5

Step-by-step explanation:

In order to find the value of a function on given input, the input is put at the place of variable in the function.

Given function is:

f(x) = (\frac{1}{2})^x

We have to find the value of function on x = 1

Putting x = 1 in function

f(1) = (\frac{1}{2})^1\\= \frac{1}{2}\\= 0.5

Hence,

The value of function on x=1 is 0.5
