When x increases from a to a + 2, y increases by a factor of 16. For which functions is this statement true?
A) y = 2(4)x
B) y = 4x + 2
C) y = 2(16)x
D) y = 16x + 2

*note that all of the X's are exponents

Respuesta :

I think the correct answer would be option B. When x increases from a to a + 2, y increases by a factor of 16. The function that best describe this would be y = 4^(x + 2). Hope this answers the question. Have a nice day. Feel free to ask more questions.
