Answer:
The input x = 1 has many outputs.
The graph is a vertical line.
Step-by-step explanation:
Hi there!
A function is defined as a relation that only gives one output for every given input. For every x-value, there is only one y-value.
Because the x-value of 1 gives us an infinite number of y-values, this is therefore not a function.
More generally, no vertical line is a function for this reason.
I hope this helps!

Answer:

Step-by-step explanation:
The formula for the volume of a cone is:

Given:
- Radius = 2cm
- Height = 9cm
Let's plug these into the equation:

Now solve:

Therefore, the volume of the cone is 37.7cm^3.

Answer:
± sqrt(3)i = x
Step-by-step explanation:
0 = x^2 +3
Subtract 3 from each side
-3 =x^2 +3-3
-3 =x^2
Take the square root of each side
±sqrt(-3) = sqrt(x^2)
±sqrt(-3) = x
We can split sqrt(-3) into sqrt(3) sqrt(-1) and we know that the sqrt(-1) is i
± sqrt(3)sqrt(-1) = x
± sqrt(3)i = x
