Answer:

f(x - 1) = 3x - 8

Step-by-step explanation:

To find f(x - 1) substitute x = x - 1 into f(x), that is

f(x - 1) = 3(x - 1) - 5 = 3x - 3 - 5 = 3x - 8

C. The difference of the medians is 4 times the interquartile range.

Step-by-step explanation:

The diagram show two box plots.

Mahoney's box plot:

Median $=33$

Interquartile range $=34-32=2$

Martin's box plot:

Median $=41$

Interquartile range $=42-40=2$

The interquartile ranges are the same.

The difference of the medians $=41-33=8$

Hence, the difference of the medians is 4 times the interquartile range.
