Select the correct locations on the graph.
Select the lines that represent functions.

The line on the bottom and and the parabola on the top are functions.

Step-by-step explanation:

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

The Circle:

Take x = 5 for example. When you look there, there are two y-values for x=5:

y = -1 and y = 1. This is not possible, so the circle is not a function.

The Half-Circle:

Take x = 2 for example. When you look there, there are two y-values for x=2:  y = 2 and y = -1. This is not possible, so the half-circle is also not a function.

The Helix (on the far left side):

Take x = -4 for example. When you look there, there are two y-values for x=-4:  y = 4 and y = -3. This is not possible, so the helix is also not a function.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
