Answer:

3i

Step-by-step explanation:

Square root -9

√(-9) = (3i)(3i)

Note that the "imaginary number" is a non-existent number. Note that in the rules of imaginary numbers: i * i = i² = -1

It is 3i.
The square root of -9 is the square root of -1 times the square root of 9.
So: the square root of 9 is 3, and the square root of -1 is called i (this doesn't actually exist, it's just imaginary).
Then, the square root of -9 is 3i.

Which graph of a relation is also a function ?
Illusion [34]

Answer:

B

Step-by-step explanation:

A graph is only a function when there is only one y value for each x value.

A trick is to draw a line through some points on the x-axis, and if the line goes through more than one point. Then it is not a function. (See picture)

Sorry, not all the lines are straight, but you get the point. B is the only one that doesn't have more than one point on the lines I drew.
