Use the function below to find f(-2) f(x)=5^x

f(-2) = 0.4

Step-by-step explanation:

The given function is f(x) = 5ˣ

and we have to find the value of f (-2)

We will substitute x = -2 in the given function.

f(x) = 5ˣ

f(-2) = (5)⁻²

Since x⁻¹ =

so f(-2) =

              = 0.04

Therefore, f(-2) = 0.4 is the answer.

according to newton’s cannonball model, what happens if the cannonball's velocity is enough to overpower the pull of earth’s gravitystep-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
