I will do it step by step
(3xy^-5)^3= 27x^3y^-15
(x^-2y^2)^-4= x^8y-8
So the fraction is (27x^3y^-15)/ x^8 y^8= 27 x^-5y^-7
and the whole thing to power of -2 equals to x^10y^14/ 729

Consider the function f(x). Select all of the following that include a vertical stretch of f(x)
zhenek [66]

Answer:

F , D, A

Step-by-step explanation:

As we know vertical stretch of f(x)  happens when we chane the value of the patameter a in this general form:

y = a. f(k(x-d))+ c  

when  |a| > 1 because When |a| > 1 (when a is greater than 1), the function is stretched vertically by a dilation factor of |a|.

So we choose, F , D, A
