(n+2)! /n! how do i simplify this? show steps

  (n+2)(n+1)

Step-by-step explanation:

Write out the numerator and cancel common factors:

  (n+2)!/n! = (n+2)(n+1)n!/n! = (n+2)(n+1)

You might be expected to multiply it out:

  = n·n +2·n +n·1 +2·1

  = n² +3n +2

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
