The point P(2, −1) lies on the curve y = 1/(1 − x). a. If Q is the point (x, 1/(1 − x)), use your calculator to find the slope of the secant line PQ (correct to six decimal places) for the following values of x:

1. 1.5
2. 1.9
3. 1.99
4. 1.999
5. 2.5
6. 2.1

b. Using the results of part (a), guess the value of the slope of the tangent line to the curve at P(2,-1).
c. Using the slope from part (b), find an equation of the tangent line to the curve at P(2,-1).

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.

it is not that hard all u have to do is plot the graph
