This is not a question from a graded test or assessment. Instructions: Give me 5 points when graphing the equation. All numbers must be less than or equal to 10. All numbers must be more than or equal to -10.

Step-by-step explanation

We must plot the function:


f(x)=\log_{(1)/(2)}(x).

With values -10 ≤ x ≤ 10 and -10 ≤ y ≤ 10.

Taking into account the properties of logarithms:


\begin{gathered} \log_a(x^b)=b\cdot\log_a(x), \\ \log_a(a)=1. \end{gathered}

We evaluate the function at x = 1/2, 1, 2, 4 and 8:


\begin{gathered} f((1)/(2))=\log_{(1)/(2)}((1)/(2))=1, \\ f(1)=\log_{(1)/(2)}(1)=0, \\ f(2)=\operatorname{\log}_{(1)/(2)}(2)=\operatorname{\log}_{(1)/(2)}(((1)/(2))^(-1))=-1\cdot\operatorname{\log}_{(1)/(2)}((1)/(2))=-1, \\ f(4)=\operatorname{\log}_{(1)/(2)}(4)=\operatorname{\log}_{(1)/(2)}(((1)/(2))^(-2))=-2\cdot\operatorname{\log}_{(1)/(2)}((1)/(2))=-2, \\ f(8)=\operatorname{\log}_{(1)/(2)}(8)=\operatorname{\log}_{(1)/(2)}(((1)/(2))^(-3))=-3\cdot\operatorname{\log}_{(1)/(2)}((1)/(2))=-3. \end{gathered}

Plotting these values and the function, we get the following graph:
