Answer asap please

Answer:

(0,1) and (-2,9)

Step-by-step explanation:

A point (x,y) lies on the graph of f(x) = (\frac{1}{3} )^{x} if it satisfies the condition y = (\frac{1}{3} )^{x}

<h3>(0,1):</h3>

        x = 0 and y = 1.

This point satisfies the required condition as

        (\frac{1}{3} )^{0} = 1

Hence, this point <u>is</u> on the graph of f(x) = (\frac{1}{3} )^{x}

<h3>(3,27):</h3>

        x = 3 and y = 27.

This point doesn't satisfy the required condition as

        (\frac{1}{3} )^{3} = \frac{1}{27} ≠ 27

Hence, this point i<u>s not</u> on the graph of f(x) = (\frac{1}{3} )^{x}

<h3>(-2,9):</h3>

        x = -2 and y = 9.

This point satisfies the required condition as

        (\frac{1}{3} )^{-2} = 3^{2} = 9

Hence, this point <u>is</u> on the graph of f(x) = (\frac{1}{3} )^{x}

<h3>(-1,-\frac{1}{3}):</h3>

        x = -1 and y = -\frac{1}{3}.

This point satisfies the required condition as

        y = (\frac{1}{3} )^{-1} = 3^{1} = 3 ≠ -\frac{1}{3}

Hence, this point <u>is not</u> on the graph of f(x) = (\frac{1}{3} )^{x}
