SOLUTION: Express y as a function of x (The constant c is a positive number): ln(y+4) = 5x + ln(c)

Question 573964: Express y as a function of x (The constant c is a positive number):
ln(y+4) = 5x + ln(c)

To express y as a function of x we just have to "solve for y". To do this we need to get the y out of the logarithm. To do that we need to rewrite the equation in exponential form.

In general
is equivalent to:

Using

this pattern with the "p" being "y+4" and the "q" being "5x+ln(c)"
the fact that the base of ln is e, making the "a" an "e"

we get (hold on!):

Now we just need to subtract 4 from each side:

We now have y as a function of x!
