Explain what the vertical line test is and how it is used.​

Mathematics
1 answer:
tangare [24]3 years ago
5 0

Answer:

The vertical line test is a way to figure out if a figure on a graph is a function. Imagine a vertical line goes across the graph from left to right. If the line touches two points at the same time, it's not a function.

Identify the number that does not belong with the other three. Explain your reasoning.
mojhsa [17]

Answer:

To identify which integer does not belong with the rest, we must first evaluate each.

Step-by-step explanation:

  • [25.6...] is already evaluated. Therefore, let's move on to Integer <em>b: </em>\sqrt{x}, where is <em>x </em>is 48.

  • 48 = 2 * 24--> 2 * 12--> 2 * 6--> 2 * 3
  • √48 = \sqrt{2} * 2 * 2 * 2 * 3
  • We have 1 perfect sqaure: \sqrt{2} * 2
  • When we multiply, we receive 2.
  • Therefore, 2 * \sqrt{2 * 3}

  • When -51/2 is relatively prime, we receive -25 1/2

  • Finally, the last integer is already simplified.

Based on these results, you may determine the number that does not belong with the other three, whether than is through means of irrationability, value, absolte value, or whatever other means you decide.

Determine the x- and the y-intercepts of these graphs. a) y = x-2​
Ivanshal [37]

Answer:

y-intercept = (0, -2)

x-intercept = (2, 0)

Step-by-step explanation:

The y-intercept is the value of y when x = 0. Therefore, Given the linear equation, y = x - 2:

Let x = 0:

y = 0 - 2

y = -2.

Therefore, the y-intercept of the linear equation, y = x - 2  is (0, -2).

The x-intercept is the value of x when y = 0.

Therefore, let y = 0:

y = x - 2

0 = x - 2

Isolate x by adding 2 to both sides of the equation:

0 + 2 = x - 2 + 2

2 = x

Therefore, the x-intercept is (2, 0).
