Question

How does the graph of g(x) = −(x + 3)^4 compare to the parent function of f(x) = x^4?

Answer 1

Answer:

c: g(x) is shifted 3 units to the right and reflected over the x-axis

Answer 2

Answer: Option D

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

Step-by-step explanation:

If we have a function f(x) and make a transformation of the form:

$g (x) = f (x + h)$

Then it is true that:

If $h> 0$ the graph of g(x) is equal to the graph of f(x) displaced h units to the left

If $h$ the graph of g(x) is equal to the graph of f(x) displaced h units to the right

Also if we have a function f(x) and perform a transformation of the form:

$g (x) = -f (x)$

Then it is true that:

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

In this case $f (x) = x ^ 4$ and $g (x) = -(x + 3) ^ 4$

So

$g(x) = -f(x+3)$

Then $h = 3> 0$. Therefore the graph of g(x) is equal to the graph of f(x) displaced 3 units to the left and reflected on the x axis

The answer is the option D
