1. What is an approximate average rate of change of the graph from x = 2 to x = 5, and what does this rate represent? 2. Describe the constraints of the domain

Step-by-step explanation:

1), Average rate of change of a function in the interval [a, b] is given by,

   Average rate of change =

   From the given graph,

   Rate of change in the interval from x = 2 to x = 5,

   Average rate of change =

                                            =

                                            = 20

2). Domain of the function → (-∞, ∞)

   Or Domain → set of all real numbers.  

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
