Answer: a) 
Step-by-step explanation:
Since we have given that

a.) Find the inverse of f(x) and name it g(x).
Let f(x) = y
So, it becomes
Switching x to y , we get


b) . Use composition to show that f(x) and g(x) are inverses of each other.

Similarly,

so, both are inverses of each other.
c) Draw the graphs of f(x) and g(x) on the same coordinate plane.
As shown below in the graph , Since for inverse function we need an axis of symmetry i.e. y=x
And both f(x) and g(x) are symmetry to y=x.
∴ f(x) and g(x) are inverses of each other.

Answer:
The new employee burn <u>1756 cookies</u> in the course of the day.
Step-by-step explanation:
Given:
Mr. Edwards hired a new employee to work in his bakeshop. In one hour, this employee burned 439 chocolate chip cookies, which represented 25 percent of all the cookies the employee burned in that day.
Now, to find the cookies the new employee burn in the course of the day.
Let the cookies the new employee burn in the course of the day be 
Number of chocolate chip cookies new employee burned = 439.
Percent this represented of all the cookies the employee burned in that day = 25%.
Now, to get the cookies the new employee burn in the course of the day we put an equation:



<em>Dividing both sides by 0.25 we get:</em>

Therefore, the new employee burn 1756 cookies in the course of the day.
Answer:
x ≤8/5
Step-by-step explanation:
6x - 9 ≥ 11x - 17
Subtract 6x from each side
6x -6x-9 ≥ 11x - 17-6x
-9 ≥ 5x- 17
Add 17 to each side
-9+17≥ 5x - 17+17
8≥ 5x
Divide each side by 5
8/5≥ 5x /5
8/5≥ x
