Question

Solve for x so where would you plot it

Answer 1

Explanation:

f(x) = 1/2 .2^x

We need to fill the table by putting values of x in the given f(x)

x = -2

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

f(x) = 1/2.1/2^2

f(x) = 1/2.1/4

f(x) = 1/8 = 0.125

y=0.125

x = -1

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

f(x) = 1/2.1/2^1

f(x) = 1/2.1/2

f(x) = 1/4 = 0.25

y=0.25

x = 0

f(x) = 1/2 .2^(0)

f(x) = 1/2. 1

f(x) = 1/2 = 0.5

y=0.5

x = 1

f(x) = 1/2 .2^(1)

f(x) = 1/2.2

f(x) = 1

y=1

x = 2

f(x) = 1/2 .2^(2)

f(x) = 1/2.4

f(x) = 2

y=2

x = 3

f(x) = 1/2 .2^(3)

f(x) = 1/2.8

f(x) = 4

y=4

Now we will plot these points. The graph is shown in the graph below.
