How to do this? (#21 and #23)

the graph of g is a transformation of the graph of f. write a rule for g.

Step-by-step explanation:

f(x) + n - shift the grapf n units up

f(x) - n - shift the grapf n units down

f(x + n) - shift the grapf n units to the left

f(x - n) - shift the grapf n units to the right

-f(x) - reflection about the x-axis

f(-x) - reflection about the y-axis

============================================

Look at the picture.

move the graph 2 units to the right and 1 unit up

move the graph 4 units down

reflection the graph about the X axis.

21. g(x) = f(x-1); 23. g(x) = -ƒ(x)  

Step-by-step explanation:

21. ƒ(x) = log₃x

The graph is shifted one unit to the right.

One unit must have been subtracted from x.

g(x) = -f(x-1) = log₃(x-1)

Figure 1 shows ƒ(x) (blue) and g(x) (green) shifted one unit to the right,

23.

The graph is inverted.

ƒ(x) must have been multiplied by -1.

g(x) = -ƒ(x)

Figure 2 shows ƒ(x) (purple) and g(x) = -ƒ(x) (black).

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

30–31 . . . . . . . . . . . . 0.001503

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497

the correct option is b
