Which of the following is the inverse of y is equal to 12 to the x th power ?
Answer
A
y is equal to the log base 1 over 12 of x
B
y is equal to the log base x of 12
C
y is equal to the log base 12 of x
D
y is equal to log sub 12 1 over x
Explanation
To find the inverse of y = 12^x, switch x and y: x = 12^y. Solving for y gives y = log base 12 of x, so the correct choice is “y is equal to the log base 12 of x.”
