Explain how to determine if the following relation is a function.

Mathematics

solong [7]2 years ago

Answer:

The given relation is not a function

Step-by-step explanation:

  • The relation becomes a function if every x-value has only one y-value
  • A function is a relation in which each input (x) has only one output (y)

<em>To test the graph is a function or not, draw a vertical line intersects the graph in different positions, if the line cuts the graph in just one point in all positions, then the graph represents a function.</em>

<em />

From the given figure

∵ The endpoint of the diameter of the semi-circle are (0, -2), (0, 2)

→ The x-coordinate = 0 has two values of y = -2, 2

∴ At x = 0, y = -2 and 2

∴ Not every x has only one y

∴ The given relation is not a function

<em>If you draw a vertical line intersects the semi-circle in different positions, it will intersect the semi-circle in 2 points, So the graph does not represent a function </em>

26 = b.

Alors, la grande base est 26 cm et le petit base serait 26/3 = 8.67 cm arrondi.

ZanzabumX [31]

The amount more of rain that fell in those three days than normally falls in July and August combined was 31.19 cm.

<h3>How much more rain fell in those three days?</h3>

The amount of rain in those three days was 41.2 cm.

The combined normal rain July and August is:

= 6.36 + 3.65

= 10.01 cm

The difference is therefore:

= 41.2 - 10.01

= 31.19 cm
