The rate of change of function is: 10

Further explanation:

The formula for rate of change is:

Rate\ of\ change = \frac{f(x_2)-f(x_1)}{x_2-x_1}

Given

f(x) = x^2-4x\\x_1 =5\\x_2=9\\So,\\f(x_1) = f(5) = (5)^2-4(5)\\=25-20\\=5\\f(x_2) = f(9) = (9)^2-4(9)\\=81-36\\=45

Putting the values in the formula:

Rate\ of\ change = \frac{f(9)-f(5)}{9-5}\\=\frac{45-5}{9-5}\\=\frac{40}{4}\\=10

The rate of change of function is: 10

Leto [7]

Answer:

The 1st graph will be perfectly matching the conditions.

Step-by-step explanation:

A wholesaler requires a minimum of 4 items in each order from its retail customers.

The manager of one retail store is considering ordering a certain number of sofas, x and a certain number of pillows that come in pairs, y.

Therefore, for y = 0, x ≥ 4 and for x = 0, y ≥ 2 to make the order of 4 items or more.  

Therefore, the equation for the order to be of 4 items will be  

x + 2y = 4.

So, the 1st graph will be perfectly matching the conditions. (Answer)

Answer:

(2x-3) (2x+3)

zeros, x intercepts:  -3/2, 3/2

Step-by-step explanation:

4x^2 -9

We know the difference of squares is a^2 -b^2

This factors into (a-b) (a+b)

Let 4x^2 =a^2  

Taking the square root

2x =a

Let b^2 =9

Taking the square root

b= 3

(4x^2-9 ) = (2x-3) (2x+3)

To find the zeros, we set the equation equal to zero

(4x^2-9 ) = (2x-3) (2x+3) =0

Using the zero product property

2x-3 =0   and 2x+3 =0

2x-3+3 = 0+3                    2x+3-3 = 0-3

2x=3                                  2x=-3

Divide by 2

2x/2 = 3/2                               2x/2 = -3/2

x = 3/2                                       x = -3/2

These are the zeros of the equation (which are also the x intercepts)
