9) Suppose that the function f(x) is the parrent function and the graph of the function g(x)=f(x)-a can be obtained from the graph of the parrent function f(x) by shifting down a units.
Rewrite the expression for the function in the following way:

1. **A(x)=(f(x)-f(a))/(x-a)
*A is the name of this average rate of change function
*x - a represents the change in the input of the function f
*f(x) - f(a) represents the change in the function f as the input changes from a to x
From table: f(5)=-2
f(9)=14
(f(5)-f(9))/(5-9)=(-2-14)/-4=4
The average rate of change of over the interval from x = 5 to x = 9 is 4.

2. f(x)=4x²+6x, g(x)=2x²+13x+1
(f/g)(x)=(4x²+6x)/(2x²+13x+1)
Using the table of values- x:4,5,6,7,8,9
f(x): 88/85,155/116,180/151,238/190,304/233,378/280

3. f(x)=x²-6x+8, g(x)=x-2
f(x)=g(x)⇒x²-6x+8=x-2⇒x²-6x-x+8+2=0, x²-7x+10=0
x₁,₂=(7⁺₋√(7²-4*10))/2=(7⁺₋3)/2
x₁=5, x₂=2
Using the table of values solution is x=5 because 2 doesn't exist in the table of values.

B. [3,5]

Step-by-step explanation:

The rate of change of a function is the same as the slope between two given points from that same function,

Hence,

all we need to do is use the slope's equation, that is

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

And eval it in every couple of ordered pairs given from the table we obtain the following>

The rate of change from g(x) is 4 (its slope)

Hence, the interval when the rate of change of f(x) is greater than g(x) is from x=3 to x=5

Business

Consider a firm with an EBIT of $11,400,000. The firm finances its assets with $51,800,000 debt (costing 7.4 percent) and 10,900,000 shares of stock selling at $8.00 per share. The firm is considering increasing its debt by $25,000,000, using the proceeds to buy back shares of stock. The firm is in the 30 percent tax bracket. The change in capital structure will have no effect on the operations of the firm. Thus, EBIT will remain at $11,400,000. Calculate the EPS before and after the change in capital structure and indicate changes in EPS. (Round your answers to 3 decimal places.)
