A convex figure with three sides is triangle. The sum of the measures of all interior angles of the triangle is 180°.
Let be interior angles of this triangle. Then
Find exterior angles of this triangle:
1. is exterior angle adjacent to the interior angle
2. is exterior angle adjacent to the interior angle
3. is exterior angle adjacent to the interior angle
The sum of the measures of all exterior angles is
Answer: 360°
Answer:
f(x) = -√(x-4) + 2
Step-by-step explanation:
(a) Start with the basic function: f(x) = √x.
This would be the top half of a horizontal parabola opening to the right (always positive).
(b) The range is y < 2. This includes negative numbers, so the function must be f(x) = -√x.
(c) The function starts at x = -4. We must shift it four units to the left. We do that by adding four units to x. The function must be f(x) = -√(x + 4). The domain is x > -4.
(d) The function starts at y = 2. We must shift it up two units. We do that by adding two units to y. The function must be f(x) = -√(x+4) + 2. The range is y < 2.
The figure below is the graph of f(x) = -√(x+4) + 2.
