Pre-Calculus problem

Question

A function f is given, and the indicated transformations are applied to its graph (in the given order). Write the equation for the final transformed graph.

f(x)= \root(4)(x); reflect in the y-axis and shift upward 4 units.

I tried my answer as " y= -\root(4)(x)-4 and it was wrong.

Answer 1

To reflect over the y-axis the x value is made negative, i.e.,

y = (√-4x) + 4
