Which logarithmic graph can be used to approximate the value of y in the equation 5y = 12?

I really think it's D. Am I right, please explain why?

Answer 1

Answer:

The graph of function f of x equals log base 5

So yes , D

Answer 2

Answer:

The correct option is D.

Step-by-step explanation:

The given equation is

$5^y=12$

Taking log with base five on both the sides.

$log_{5}5^y=log_{5}12$

$y=log_{5}12$                                 $[\because log_aa^x=x]$

This function can be written as

$y=log_{5}x$

Where, x=12.

Substitute x=5 in the above function.

$y=log_{5}5=1$

At x=5, the value of function is 1.

Only in option D, the value of function is 1 at x=5.

Therefore, the correct option is D.
