The percentage change is computed by
  percentage change = ((new value)/(original value) - 1) × 100%

Problems 1–3 all use this formula.

1. (3.25/.99 - 1)×100% ≈ 228.3%
2. (2.75/3.25 - 1)×100% ≈ -15.4%
3. (2.75/.99) - 1)×100% ≈ 177.8%

4. The formula for simple interest is
  I = Prt
where P is the principal amount, r is the rate, t is the number of periods, and I is the interest earned. Substitute the given values and solve for t.
  400 = 5000·0.04·t
  400/200 = t = 2

To stretch it vertically, you'll need a coefficient greater than 1 in front of the x. If you want to flip the graph over the x axis that coefficient needs to be negative. So it can only be D

state the domain, the range, and the intervals on which function is increasing, decreasing, or constant in interval notation
erma4kov [3.2K]

Answer:

  • domain (-∞, ∞)
  • range (-∞, 4]
  • increasing (-∞, 0)
  • decreasing (0, ∞)
  • constant (only at x=0, not on any interval)

Step-by-step explanation:

The graph is of the equation y = -x^2 +4. It is a polynomial of even degree, so has a domain of all real numbers: (-∞, ∞).

The vertical extent of the graph includes y=4 and all numbers less than that:

  range: (-∞, 4]

The graph is increasing to the left of its vertex at x=0, decreasing to the right.

  increasing (-∞, 0); decreasing (0, ∞)

There is no interval on which the function is constant. It has a horizontal tangent at x=0, but a single point does not constitute an interval.
