Match the y-coordinate with the given x-coordinate for the equation y = log2x. x coordinates 8 4 2 1 1/2 y coordinates -1 2 1 0 3

Step-by-step explanation:

y = log2 x

Convert to exponential form

x = 2^y

when x = 8 , 8 = 2^y  so y = 3

          x = 4 , 4 = 2^y so y = 2

the other values are found in the same fashion.

x = 2 , y = 1

x = 1 y = 0

x = 1/2, y = -1

use formula for the circle a=3.14
