What is the domain of the following exponential function f(x)=(4/5)^x

Hello from MrBillDoesMath!

 The domain is the set of real numbers.

the full real number system

Discussion:

f(x) = (4/5)^x is defined for all x as the underlying function  (4/5)^x is defined for all x. Therefore the domain is the set of real numbers.

Thank you,

MrB

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
