Using permutations, it is found that there are 12 ways to pick a sequence of two different letters of the alphabet that appear in the word Crab .
The order in which the letters appears is important, as for example, ab is a difference sequence than ba, hence the <em>permutation formula</em> is used.
Permutation formula:
The number of possible permutations of x elements from a set of n elements is given by:
In this problem, 2 letters are picked from a set of 4, hence:

Answer:
A parabola with an x-intercept of (3, 0)
Step-by-step explanation:
We can immediately rule out the first and third options, because the equation of a second degree function is a parabola.
Your equation is
ƒ(x) = x² - 6x + 9 = 0
We can factor this equation as
ƒ(x) = (x - 3)²
The parent parabola, y = x², has its x-intercept at (0,0).
Your function subtracts three from x, so the intercept is shifted three units to the right.
The graph of your function is a parabola with an x-intercept of (3, 0).
The figure below shows the graph of your function shifted three units by subtracting three from x.
Each year, the current balance is multiplied by 1.07.
After 8 years, we'll have multiplied it by 1.07 eight times.
This can be written as
