The most likely answer is b
Answer:
The mean.
Step-by-step explanation:
The mean is not robust.
The presence of an outlier greatly affects the value of a mean.
An example will illustrate this.
Find the mean of the numbers 2 3 5 6 34.
34 is an outlier. The mean = (2+3+5+6+34) / 5 = 10.
Now if we replace the outlier with a number closer to the others:
Say we have 2 3 5 6 8 :
The mean = (2+3+5+6+8) / 5 = 4.8 which is a much truer measure of centrality than 10.
G (x) = x + 1 (fog) (x) = x 2 + 3x + 1 ⇒ (fog) (x) = x 2 + 3x + 1 ⇒ f (g (x)) = x 2 + 3x + 1 ⇒ f (x + 1) = x 2 + 3x + 1 Eg x + 1 = p, then x = p - 1. ⇒ f (p) = (p - 1) 2 + 3 ( p - 1) + 1 ⇒ f (p) = p 2 - 2p + 1 + 3p - 3 + 1 ⇒ f (p) = p 2 + p - 1 So f (x) = x 2 + x - 1 - ->
ANSWER IS : x 2 + x - 1
