Answer:
18.4 what the right answer
Step-by-step explanation:
Answer:
4. (w² + 6)(w² - 6)
Step-by-step explanation:
w^4 - 36
(w² + 6)(w² - 6)
We are given the functions

and

.
let's consider some pairs in the graph of both functions.
in

we have (-2, 4), (2, 4), (3, 9), (-5, 25)
in

we have (-2, -4), (2, -4), (3, -9), (-5, -25)
so for the same values of x, we have y's of equal value, but different sign.
This means that the functions are the reflections of each other with respect to the x-axis.
