Question 573964
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.<br>
In general
{{{log(a, (p)) = q}}} is equivalent to:
{{{a^q = p}}}
Using<ul><li>this pattern with the "p" being "y+4" and the "q" being "5x+ln(c)"</li><li>the fact that the base of ln is e, making the "a" an "e"</li></ul>we get (hold on!):
{{{e^(5x + ln(c)) = y + 4}}}
Now we just need to subtract 4 from each side:
{{{e^(5x + ln(c)) - 4 = y}}}
We now have y as a function of x!
