Is it a function and whats the domain and range
Picture below

Function? Not a function

Why? For a single input of -3, we're getting two outputs of 2 and 6.

The domain is {-6, -3, -1, 3}.

The range is {2, 4, 6, 7}.

Step-by-step explanation:

Hi there!

A function is a special type of relation where for every input of x, you would only get 1 output of y.

In this question, we're given a mapping diagram on the left. The ellipse on the left shows us the domain, also known as the inputs of x. The one on the right shows us the range, also known as the outputs of y.

Notice how the input of -3 gives us two outputs, 2 and 6. Because we're getting two outputs from one input, this is NOT a function.

The domain is {-6, -3, -1, 3}.

The range is {2, 4, 6, 7}.

I hope this helps!

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
