Answer:

(x - 1)(x + 1)(x + 3).

Step-by-step explanation:

x^3 + 3x^2 - x - 3 Factor by grouping:

= x^2(x + 3) - 1(x + 3) x+3 is common .

= (x^2 - 1)(x + 3) x^2 - 1 is the difference of 2 squares.

Let f(x)=cos(arctanx). What is the range of f?

Alenkasestr [34]

-π/2 < arctan(x) < π/2

So cos(π/2) < cos(arctan(x)) < cos(0)

0 < cos(arctan(x)) < 1
