Answer: OPTION D.

Step-by-step explanation:

Below are some transformations for a function f(x):

If -f(x), then the function is reflected over the x-axis.

If f(-x), then the function is reflected over the y-axis.

If f(bx)  and b>1, then the function is horizontally compressed.

If  f(bx)  and 0 < b, then the function is horizontally stretched.

In this case you know that the parent function is:

y=x^3

According to the information given in the exercise, the parent function IS horizontally stretched by a factor of \frac{1}{5} and it is also reflected over the y-axis.

Therefore, based on the transformations explained before, you can notice that the transformation is:

f(-bx)

Where 0 < b

Therefore, the equation of the transformed function is:

y=(-\frac{1}{5}x)^ 3

What is the percent of decrease from 110 to 77
Charra [1.4K]
If you want to easily find the solution you can use your calculator.
Just divide 77 by 110 and see the result.
77/110 = 0.7 = 7/10 = 70/100 = 70% 
100% - 70% = 30%

Explanation
110*x=77
x=77/110, but the answer is not a percent
So 77/110 = ?/100  => ?=77*100/110=70 => 70%
But since 70% does not represent a percentage decreasement, we need to subtract it from the 100% 
100% - 70% = 30%
