The set of ordered pairs (-1,8), (0, 3), (1, -2), and (2-7) represent a function. What is the range of the function?

Rama09 [41]

Answer:

Range is given by the second option: $y=$ { $-7,-2,3,8$ }.

Step-by-step explanation:

Range is the set of possible $y$ values in a given function.

Here, the function is defined by the following ordered pairs:

$(-1,8),(0,3),(1,-2),(2,-7)$

The y values of the function are $y=$ { $-7,-2,3,8$ }

Therefore, the range is given as $y=$ { $-7,-2,3,8$ }.

So, the second option is correct.

Cos sec² a - cot²a=1

alex41 [277]

Answer:

We want to prove the relation:

cosec(a)^2 - cot(a)^2 = 1

where:

cosec(a) = 1/sin(a)

cot(a) = 1/tg(a) = cos(a)/sin(a)

We can start with the relationship:

cos(a)^2 + sin(a)^2 = 1

Now, let's divide by sin(a)^2 in both sides:

(cos(a)^2 + sin(a)^2)/sin(a)^2 = 1/sin(a)^2

cos(a)^2/sin(a)^2 + sin(a)^2/sin(a)^2 = (1/sin(a))^2

(cos(a)/sin(a))^2 + 1 = (1/sin(a))^2

and remember that:

cosec(a) = 1/sin(a)

cot(a) = 1/tg(a) = cos(a)/sin(a)

Then we can write:

(cos(a)/sin(a))^2 + 1 = (1/sin(a))^2

as:

cot(a)^2 + 1 = cosec(a)^2

1 = cosec(a)^2 - cot(a)^2

And this is the relation we wanted to prove.
