Gven

The lograthmic function, lograthmic fu

$y=\log_4x$

To find:

a) Rewrite the function in exponential form.

b) For each given value of y, find the value of x to complete the ordered pair.

c) The graph of the function.

Explanation:

It is given that,

$y=\log_4x$

a) Since,

It is known that,

$\begin{gathered} y=\log_ax \\ \Rightarrow x=a^y \end{gathered}$

Then,

$x=4^y$

Hence, the exponential form of the function is,

$x=4^y$

b) Also,

For y = -2,.

The value of x is given by,

$\begin{gathered} \\ \Rightarrow x=4^{-2} \\ \Rightarrow x=\frac{1}{4^2} \\ \Rightarrow x=\frac{1}{16} \end{gathered}$

Hence, the ordered pair is (1/16, -2).

For y = -1,

$\begin{gathered} x=4^{-1} \\ x=\frac{1}{4} \end{gathered}$

Hence, the ordered pair is (1/4, -1).

For y = 0,

$\begin{gathered} x=4^0 \\ x=1 \end{gathered}$

Hence, the ordered pair is (1, 0).

For y = 1,

$\begin{gathered} x=4^1 \\ x=4 \end{gathered}$

Hence, the ordered pair is (4, 1).

For y = 2,

$\begin{gathered} x=4^2 \\ x=16 \end{gathered}$

Hence, the ordered pair is (16, 2).

c) Also, the graph of the given function is,
