Q. What is the inverse of the function y=log3x ?(A) y=x3(B) y=logx3(C) y=3x(D) x=3y
Identify Function Components: Identify the original function and its components.The original function is y=log3(x), which means that 3 raised to the power of y equals x.
Write in Exponential Form: Write the original function in exponential form.To find the inverse, we switch x and y and solve for the new y. So, we rewrite the equation as x=3y.
Solve for Inverse Function: Solve for the new y to express the inverse function.To express the inverse function, we solve for y, which gives us y=log3(x). Since we have switched x and y, the inverse function is x=3y.
Check Answer Choices: Check the answer choices to see which one matches the inverse function.The correct answer choice that matches x=3y is (3) y=3(x), since it represents the inverse relationship between x and y.
