Use the graph below to answer the following question:

what is the average rate of change from x = 1 to x = 3?

a.) −4
b.) −2
c.) 2
d.) 4

 The correct option is (C) 2.

Step-by-step explanation:  We are given to find the average rate of change of the given graph from x = 1 to x = 3.

Let the graphed function be denote by y = f(x).

From the graph, we note that

f(1) = -3   and  f(3) = 1.

We know that

the average rate of change of a function g(x) from x = a to x = b is given by

Therefore, the average rate of change of the graphed function from x = 1 to x = 3 is given by

Thus, the required average rate of change is 2.

Option (C) is CORRECT.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
