Please help me with domain and range of graphs Part 1​

Mathematics

dybincka [34]3 years ago
8 0

Answer:

  • see the attached for domain
  • Range: (-∞, 4], [3, ∞), [-3, 1]

Step-by-step explanation:

The domain is the horizontal extent of the graph. When the graph has arrows on the end, it extends to infinity in the indicated direction.

__

The range is the vertical extent of the graph.

<u>Left Graph</u>

We assume the curve is intended to touch, not cross, the line y=4, so the range is ...

  range: (-∞, 4]

__

<u>Middle Graph</u>

We assume the graph continues along the line y=3 to the right indefinitely. Then this value is the minimum of the range.

  range: [3, ∞)

__

<u>Right Graph</u>

The low point on the graph is at y=-3, and it looks like the graph continues to the right along the line y=1. Then the range is ...

  range: [-3, 1]

 PLEASE HELP !!!!!!!!!! Alexia spent 3 minutes working on each of her math problems and 4 minutes on each of her science problem
Lunna [17]
The correct answer to this problem is the third statement which is "Alexia completed 20 math problems and 10 science problem". The following conditions are stated in the problem:
Alexia can answer 3 minutes on each math problem
Alexia can answer 4 minutes on each science problem
She worked more than 60 minutes
We have the inequality 3x + 4y > 60 where x represents the total number of math problem while y represents the total number of the science problem.
in our answer, we have x=20and y=10
3*20 + 4*10 > 60
60 + 40 > 60
100 > 60

Therefore, our answer is correct.

How can you use the measures of center and the range to compare two populations?
DochEvi [55]

The measure of center and range to be used to compare the population is the median and the inter quartile range.

<u>Explanation:</u>

You utilize the median and the interquartile range (IQR) to portray skewed distributions of information. To look at two populaces, utilize the mean and the MAD when the two populations are symmetric. Utilize the middle and the IQR when possibly one or the two circulations are slanted.

In statistics and probability theory, the median is the worth isolating the higher half from the lower half of an information test, a populace or a likelihood circulation. For an informational collection, it might be thought of as the "center" esteem.

1. What values of a, b, and c would you use in the quadratic formula for the following equation?
kiruha [24]
Answer: See each part below.

1) A, B, and C are the coefficients in order when it equals 0. Move over the 4 and you have 5, 9, -4 or Choice B.

3) If you graph the equation, it will be above the x-axis. Therefore, it has no roots. Choice D

4) Choice A is correct. Use the coefficients: A = 4, B = 3, C = -10. Simply plug those into the quadratic equation and you will get -2 and 1.25.
