Answer:

The correct option is 2. The range of the function is {-6,-18}.

Step-by-step explanation:

The given function is

$f(x)=3x-12$

Domain is the set of all possible inputs and range is the set of all possible outputs.

It is given that the domain of the function is {-2,2}.

For x=-2.

$f(-2)=3(-2)-12=-6-12=-18$

For x=2.

$f(2)=3(2)-12=6-12=-6$

Therefore the range of the function is {-6,-18} and option 2 is correct.

Find the values of x and y.

Artist 52 [7]

Hi! Hope this helps, and if it does, please mark brainliest!

Answer:

y = 43 and x = 90

Step-by-step explanation:

We know that a triangle is 180 degrees (each side equals 180 since they are their own triangles) We will focus on the left triangle. Since x is a right angle, it is 90 degrees. Since there is a slash across the two sides of the main triangle, that means both sides are equal. This means that the bottom left angle, the one above b, is equal to 47 degrees. That means we know two angles out of 3. For the sake of simplicity, the bottom left angle, the one above b, is point z. So point z is 47, and x is 90, added they are 137. Subtract that from 180, you will get 43. 43 is y.
