Help with domain and range.

Mathematics
1 answer:
Westkost [7]3 years ago
7 0

Answer:Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

3 1/4 - 2 1/3 what is the answer please explain
anastassius [24]

Answer:

it is 0.91<u>6 (</u>the six is repeated. a line under a number means repeated in this case)

Step-by-step explanation:

First you take 3 1/4 and turn it into 13/4 and turn 2 1/3 into 7/3 and transform those into decimals 13/4 = 3.25 and 7/3 = 2.<u>3</u> and subtract which is 0.95 plus the fact that the three is repeated which gets your answer of 0.91<u>6</u> however you should say that if they want you to simplify it to two/three decimals, it is 0.95 but if they want it exact it is 0.91<u>6</u> with the six being repeated

It says to place points on them but i still don't get it. help please.
xxTIMURxx [149]

Answer: A'=(1, 3); B'=(-3, 4);C'=(3, 0); D'=(-2, 5)

You can check the PNG attached as well.

Step-by-step explanation:

You need to represent the symmetry of every given points respet to the line

y = 2

In that case, the line beeing paralell to the x- axis, x- value of the symmetry is the same of the given point and y = 2 is the middle between both points.

Point A(1, 1)

x_{A} = 1\\ x_{A'} = 1 \\\\\frac{y_{A} +y_{A'} }{2} =2\\y_{A'} = 4 - y_{A} = 4 - 1 = 3

Point B(-3, 0)

x_{B} = 1\\ x_{B'} = 1 \\\\\frac{y_{B} +y_{B'} }{2} =2\\y_{B'} = 4 - y_{B} = 4 - 0 = 4

Point C(3, 4)

x_{C} = 1\\ x_{C'} = 1 \\\\\frac{y_{C} +y_{C'} }{2} =2\\y_{C'} = 4 - y_{C} = 4 - 4 = 0

Point D(-2, -1)

x_{D} = 1\\ x_{D'} = 1 \\\\\frac{y_{D} +y_{D'} }{2} =2\\y_{D'} = 4 - y_{D} = 4 - (-1) = 4 + 1 = 5
