Question

Which logarithmic graph can be used to approximate the value of y in the equation 3^y = 7? 20 POINTS

Answer 1

Then,

3^y = 7, is equivalent to y = log_3(7)

We need to find which graph goes like log_3(x). For x =3, log_3(3) = 1, for x = 9, lo_3(9)=2, so .....

The first one!

Answer 2

Answer with explanation:

The exponential function is

`3^y=7\\\\ \text{taking log on both sides}\\\\y\log3=\log7\\\\y=(\log7)/(\log3)\\\\y=\log_(3)7\\\\y=(0.8450)/(0.477)\\\\y=1.77`

It is equation of a line, parallel to X axis.

Drawn the graph of the function , which cuts the y axis at ,(1.77,0).

None of the curve matches with the given Options.
