Mathematics

Answer:

Step-by-step explanation:

I'm doing seven.

<em><u>x = -2</u></em>

y = 2^(-2 -1) + 2

y = 2^(-3) + 2

y = 1/2^3 + 2

y = 1/8 + 2

y = 2.125 which is a guess on the graph.

<em><u>x = - 1</u></em>

y = (2)^(-1 -1) + 2

y = (2)^-2 + 2

y = 1/4 + 2

y = 2.25

x = 0

y = 2^(0 - 1) + 2

y = 2^(-1) + 2

y = 1/2 + 2

y = 2.5

<em><u>x = 1</u></em>

y = 2^(1 - 1) + 2

y = 2^0 + 2           If the power of a number = 0 then the result = 1. The only exception to that is 0^0

y = 1 + 2

y = 3

Eight

<em><u>x = -1</u></em>

y = (1/2)^(-1 + 1) + 2

y = 1 + 2

y = 3

<em><u>x = 0</u></em>

y = (1/2)^(0 - 1) + 2

y = (1/2)^-1 + 2             Turn the 1/2 upside down

y = 2 + 2

y = 4

<em><u>x = 1</u></em>

y = (1/2)^(1 + 1) + 2

y = (1/2)^2 + 2

y = 1/4 + 2

y = 2.25

<em><u>x = 2</u></em>

y = (1/2)^(2 + 1) + 2

y = (1/2)^3 + 2

y = 1/8 + 2

y = 2.125
