I don’t know how you guys are technically taught to explain but i would say they are congruent by SAS or you could just be simple and say they lines next to the angles fepresent congruent angles

Use the graph of the function to find the domain and range of f.
Alik [6]
The domain is the x-values u insert to get corresponding y-values. In other words, the domain is the boundaries for which u can enter x valies. In this graph, we can see that the function continues infinitely upwards, not vertical shifting a bit to the sides. This means that the domain is all x belonging to the set R, since for any x value, we will get a corresponding point on the graph. For the range, it is simply the range of the y-values. From the graph, teh range is -4

What are the coordinates of the vertex of the parabola with the equation y = x2 + 2x – 3?
Sonbull [250]

Answer:

  A.  (-1, -4)

Step-by-step explanation:

The vertex can be found by converting the equation from standard form to vertex form.

<h3>Vertex</h3>

Considering the x-terms, we have ...

  y = (x^2 +2x) -3

where the coefficient of x is 2. Adding (and subtracting) the square of half that, we get ...

  y = (x^2 +2x +(2/2)^2) -3 -(2/2)^2

  y = (x +1)^2 -4

Compare this to the vertex form equation ...

  y = a(x -h)^2 +k

which has vertex (h, k).

We see that h=-1 and k=-4. The vertex is (h, k) = (-1, -4).

On the attached graph, the vertex is the turning point, the minimum.

In a certain city, the monthly cost of telephone service is given the function C = 0.10n + 18, where n is the number of calls, 1
Yuliya22 [10]

Answer:

The cost of making 60 calls a month is $20.

Step-by-step explanation:

There was a small typing mistake there. If the fixed charge is $14, the cost of n calls is given by the following equation:

C(n) = 0.1n + 14

Find the cost of making 60 calls a month.

This is C(60), that is, C when n = 60. So

C(n) = 0.1n + 14

C(60) = 0.1*60 + 14 = 20

The cost of making 60 calls a month is $20.

Explain why the vertical line test is used to determine if a graph represents a function.
iogann1982 [59]
The vertical line test is simply using a vertical line across the whole graph to see if it touches two points at the same time. This is used because a function can only create ONE output for every input. For example, you can't plug 2 into the function x^{2} and get two different answers, you'll only get one, 4. However, you can also plug in -2 to get 4. This is because two different inputs can have the same output, but one input CANNOT have two outputs. 
Therefore, if it fails the vertical line test, then it's not a function
