Given the equation:
y = 12^x
Determine the inverse of the function.
Solution:
In order to determine the inverse of the function, we simply needed to equate the function into logarithmic form.
Standard form: y = a^x
Logarithmic Form x = log a y
By basing on the given formula, we must first interchange the value of x and y, then solve for y.
x = log 12 y
y = log12x
Final answer:
y = log 12x
