Answer 2

Answer:

1) Maximum value

2)  When x < -1

3) When x >-1

4) All real numbers

5) 'The range of the function is all numbers less than or equal to 0'

Step-by-step explanation:

The function f(x) = –x² – 2x – 1.

1) The vertex is the 'maximum value.'

2) The function is increasing "when x <  -1.'

3) The function is decreasing 'when x > -1.'

4) The domain of the function is  'all real numbers'.

5) The range of the function is  'The range of the function is all numbers less than or equal to 0.'
