To determine if the inverse of the function
is also a function, we need to check if the inverse function passes the vertical line test. The vertical line test states that if any vertical line intersects the graph of a function at more than one point, then the function is not a function. In this case, the function
is a cube root function shifted 3 units to the right. The graph of this function is a curve that passes the vertical line test, meaning it is a function.To find the inverse function, we need to swap the x and y variables and solve for y. Let's start by replacing
with
:
Now, we'll swap the x and y variables:
To solve for y, we'll cube both sides of the equation:
Finally, we'll add 3 to both sides to isolate y:
So, the inverse function is
.Therefore, the answer is:D yes
