On what interval is the function f (x) = (x – 3) (x + 3) increasing?

thus, the first answer choice, y = sec x, is the correct one

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218

ya

2, 2, 2 or -4, 20, 29

step-by-step explanation:

there is two ways you can do it.
