The average rate of change from x = -1 to x = 2 is 2
<u>Solution:</u>
Given function is:
f(x) = 2x - 1
We have to find the average rate of change from x = -1 to x = 2
<em><u>The average rate of change is given as:</u></em>

<em><u>The average rate of change from x = -1 to x = 2 is given by formula:</u></em>

<em><u>Find f(2) and f( - 1)</u></em>
<em><u>Substitute x = 2 in given function</u></em>
f(2) = 2(2) - 1 = 4 - 1 = 3
<em><u>Substitute x = -1 in given function</u></em>
f( - 1) = 2(-1) - 1 = -2 - 1 = -3
<em><u>Substitute the values in above formula,</u></em>

Thus average rate of change from x = -1 to x = 2 is 2
 
        
             
        
        
        
Answer: The cost to tile the floor is $318.24.
Step-by-step explanation:
Since we have given that 
Dimensions of floor is 12 by 17 foot.
So, Area of floor would be 

As we know that 1 foot = 12 inch
So, Area of floor would be 

Dimension of brick tiles is given by

So, Area of brick tiles is given by

So, Number of clay brick would be 

cost of each clay brick = $0.72
So, Total cost of flooring would be 

Hence, The cost to tile the floor is $318.24.
