PLEASE HELP!!!!!!!!!!!!

How does the graph of g(x) = −(x + 3)^4 compare to the parent function of f(x) = x^4
A) g(x) is shifted 3 units to the right and 1 unit up
B) g(x) is shifted 3 units to the right and 1 unit down
C) g(x) is shifted 3 units to the right and reflected over the x-axis
D)g(x) is shifted 3 units to the left and reflected over the x-axis
I would rlly appreciate it!!! :)

Answer: Option D

Explanation:

If we have a main function
f (x) = x ^ 4

And we perform the transformation:


g (x) = f (x + h) = (x + h) ^ 4

Then it is fulfilled that:

If
h> 0 the graph of
f(x) moves horizontally h units to the left

If
h <0 the graph of
f(x) moves horizontally h units to the right

If we have a main function
f (x) = x ^ 4

And we perform the transformation:


g (x) = -f(x) = -x ^ 4

Then it is fulfilled that:

The graph of
g(x) is equal to the graph of
f(x) reflected on the x axis

In this case we have to:


g(x) = -(x + 3)^4 and
f(x) = x^4

Therefore
h=3>0 and
g(x) = -f(x)

This mean that: g(x) is shifted 3 units to the left and reflected over the x-axis.
