Answer:
The average rate of change of the function from x=1 to x=2 will be: 10.5                
Step-by-step explanation:
Given the function

at x₁ = 1, 
f(x₁) = f(1) =  -14/(1)² = -14/1 = -14
at x₂ = 2,
f(x₂) = f(2) = -14/(2)² = -14/(4) = -3.5
Using the formula to determine the average rate of change at which the total cost increases will be:
Average rate of change = [f(x₂) - f(x₁)] / [ x₂ - x₁]
                                         = [-3.5 - (-14)] / [2 - 1]
                                         = [-3.5 + 14] / [1]
                                         = 10.5 / 1
                                         = 10.5
Therefore, the average rate of change of the function from x=1 to x=2 will be: 10.5
