What is the domain and range of each relation?

LUCKY_DIMON [66]

Answer:

$\text{Domain of}R_1=\{-2,0,2,4\}$ and $\text{Range of}R_1=\{-3,-1,0\}$

$\text{Domain of}R_2=\{-3,-1,0,3\}$ and $\text{Range of}R_2=\{-1,0,1,2,3\}$

Step-by-step explanation:

Domain is the set of input values or x-values.

Range is the set of output values or y-values.

According to the relation mapping diagram, the relation is

$R_1=\{(-2,-3),(-2,-1),(0,0),(2,0),(4,-3)\}$

So,

$\text{Domain of}R_1=\{-2,0,2,4\}$

$\text{Range of}R_1=\{-3,-1,0\}$

In the graph 5 points are plotted. So, the relation is

$R_2=\{(-3,1),(-1,-1),(0,0),(3,2),(3,3)\}$

So,

$\text{Domain of}R_2=\{-3,-1,0,3\}$

$\text{Range of}R_2=\{-1,0,1,2,3\}$

What is the range of F(x) = -4cos2x?

MArishka [77]

Assuming you want the range of
-4cos(2x)

the range of the cosine function is -1 to 1. When that is scaled by a factor of -4, it becomes 4 to -4.

The range of F(x) is [-4, 4] in interval notation.

_____
If you want the range of
F(x) = -4cos²(x)
that range will be -4×[0, 1] = [-4, 0].

A single card is drawn from a standard 52-card deck. Let D be the event that the card drawn is a black card, and let F be the

Svetllana [295]

Answer:

$\dfrac{25}{26}$

Step-by-step explanation:

Let

D be the event that the card drawn is a black card
F be the event that the card drawn is a 10 card
F' be the event that the card drawn is not a 10 card

The probability

$Pr(D\cup F')=Pr(D)+Pr(F')-Pr(D\cap F')\\$

Note that

$Pr(D)=\dfrac{26}{52}=\dfrac{1}{2}\\ \\Pr(F)=\dfrac{4}{52}=\dfrac{1}{13}\\ \\Pr(F')=1-\dfrac{1}{13}=\dfrac{12}{13}\\ \\Pr(D\cap F')=\dfrac{24}{52}=\dfrac{6}{13}$

So,

$Pr(D\cup F')=\dfrac{1}{2}+\dfrac{12}{13}-\dfrac{6}{13}=\dfrac{25}{26}$
