Question

Tell whether the set of ordered pairs satisfies an exponential function. Explain your answer.
{(-2, 4), (-1, 2), (0, 1), (1, 0.5)}

Answer 1

Yes.
For each increment of x, the y value is halved. This can be represented by the function f(x)= 0.5^x.
The initial value here is 1 because when x=0, y=1.

Answer 2

Answer:

Yes.

For each increment of x, they value is halved.

This can be represented by the function f (x) =0.5^x. The initial value is one
