Identify the set of X-values for which f(X) is greater than or equal to 0.

Mathematics
1 answer:
Allushta [10]1 year ago
6 0

The given function is greater than or equal to 0 for the interval given as follows:

{x | x ≤ -3 or -1 ≤ x ≤ 0 or x ≥ 2}.

<h3>When a function is positive and when it is negative?</h3>

  • A function is positive when it is above the x-axis.
  • A function is negative when it is below the x-axis.

For this problem, with a closed interval, we have that the function is above for:

x ≤ -3, -1 ≤ x ≤ 0, x ≥ 2.

Hence the interval notation is:

{x | x ≤ -3 or -1 ≤ x ≤ 0 or x ≥ 2}.

A 100% increase followed by a 50% decrease
just olya [345]

Answer:

We end up with our original number

Step-by-step explanation:

Let x be our number

We increase by 100

increase = old number * 100%

increase = x*1

increase = x

New number = old number + increase

                       = x+x

                         =2x

Now we decrease by 50%

decrease = number *50%

                = 2x*.5

                =x

Final number = new number - decrease

                       = 2x-x

                         =x
