What is the function that I need to write

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

Step-by-step explanation:

The -1 moves the graph down 1

The *2 moves the figure to the right 2

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

y=mx+b

step-by-step explanation:

m slope

b y-intercept
