The answer in B. For complicated statistics reasons the Central Limit Theorem states that, for sample sizes of above 25 (or 30 depending on the text!), the distribution of sample means is approximately normal regardless of the distribution of the parent distribution

The graph of F(x) shown below resembles the graph of G(x) = x4, but it has
DerKrebs [107]

Using translation concepts, the equation of F(x) is:

A. F(x) = \frac{1}{3}x^4 - 2

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The parent function is:

G(x) = x^4

For function F(x), we have that:

  • It was shifted down 2 units, hence F(x) = G(x) - 2.
  • It was vertically compressed by a factor of 3, hence F(x) = \frac{1}{3}G(x) - 2

Then the equation is:

A. F(x) = \frac{1}{3}x^4 - 2

andriy [413]

Plug in the given values and you'll see its option 2.

x=0 , f(x)  = 0^2 + 1 = 1

x = 1 , f(x) = 1^2 + 1 = 2

x = 2, f(x) = 2^2 + 1 = 5
