Question

How do I do this I really need to know!

Answer 1

Explanation:

I'm doing seven.

x = -2

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.

x = - 1

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

x = 1

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

x = -1

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

y = 1 + 2

y = 3

x = 0

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

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

y = 2 + 2

y = 4

x = 1

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

y = (1/2)^2 + 2

y = 1/4 + 2

y = 2.25

x = 2

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

y = (1/2)^3 + 2

y = 1/8 + 2

y = 2.125
