Domain and range of the graph, is it a function?​

Mathematics
1 answer:
Elenna [48]2 years ago
4 0

Answer:

  • domain: [0, ∞)
  • range: (-∞, ∞)
  • not a function

Step-by-step explanation:

The arrows indicate the graph continues indefinitely in the direction indicated.

The domain is the horizontal extent, so is the interval from 0 to infinity, including 0.

The range is the vertical extent, so extends from negative infinity to positive infinity (all real numbers).

The graph does not pass the vertical line test: a vertical line intersects it in more than one place, so the relation is NOT a function.

TriangleABC has three sides with these lengths: AB=9, BC=40, and CA=41, What is the value of cos C?
Otrada [13]

Answer:

9² = 40² + 41² - 2(40)(41) cos(C)

81 = 1600 + 1681 - 3280 cos(C)

81 = 3281 - 3280 cos(C)

-3200 = -3280 cos(C)

cos(C) = 3200 / 3280

cos(C) = 40 / 41
