Find the equation of function after the transformation of the parent function.

The parent function is .

Parent function reflected across the x-axis means the function is multiplied by .

Since parent function is multiplied by a factor it becomes .

The parent function translated unit left, so becomes .

Then the function .

The function translated units up means add the value of function by .

Since add the value of function by , the function become changed to .

The equation of function after the transformation of the parent function .
