Answer:

Join the points found below using a curve

Explanation:

f(x) = (½)^x

x = -2, f(x) = 4

x = -1, f(x) = 2

x = 0, f(x) = 1

x = 1, f(x) = ½

x = 2, f(x) = ¼

Answer and Step-by-step explanation:

Let's plug in each of -2, -1, 0, 1, and 2 in for x in the equation
f(x)=(1/2)^x.

f(-2) =
(1/2)^(-2)=4 ----- So, plot the point (-2, 4)

f(-1) =
(1/2)^(-1)=2 ------- So, plot the point (-1, 2)

f(0) =
(1/2)^(0)=1 ------ So, plot the point (0, 1)

f(1) =
(1/2)^(1)=1/2 ----- So, plot the point (1, 1/2)

f(2) =
(1/2)^(2)=1/4 ------- So, plot the point (2, 1/4)

After plotting those points, just connect the dots and that's your graph.

Hope this helps!
