Match the y-coordinate with the given x-coordinate for the equation y = log2x.
Troyanec [42]

Logs are exponents so the log base 2 of 2 raised to the power n is just n.

y = \log_2 x

1. \log_2 8 = \log_2 2^3 = 3 \quad nope, not -1

2. \log_2 4 = \log_2 2^2 = 2 \quad nope, not 1

3. \log_2 2 = 1 \quad nope, not 3

4. \log_2 1 = \log_2 2^0 = 0 \quad YES, matches, CHOOSE ME!

5. \log_2 \frac 1 2 = \log_2 2^{-1} = -1 \quad nope, not 2

Answer: choice 4
