Question

Which relation is also a function?

A.
A dot plot graph shows on a coordinate plane passes through (4, minus 8), (2, minus 4), (2, minus 3), (1, minus 1), (0, 1), (minus 1, 2), (minus 1, 4), (minus 3, 5), and (minus 4, 7)
B. (,)
C. circle graph
A nonlinear function on a coordinate plane vertex at (minus 3, minus 2) passes through (minus 7, 0), and (minus 6, minus 4).
D.
x y

Answer 1

The relation that is also a function is described as follows:

A nonlinear function on a coordinate plane vertex at (minus 3, minus 2) passes through (minus 7, 0), and (minus 6, minus 4).

When a relation is a function?

A relation is a function if each value of the input is mapped to only one value of the output.

In this problem, we have that:

• For the dot plot graph, input 2 is mapped to -3 and -4, hence it is not a function.

• In a circle graph, each value of x is mapped to two values of y, hence it is not a function.

Hence a function is given by:

A nonlinear function on a coordinate plane vertex at (minus 3, minus 2) passes through (minus 7, 0), and (minus 6, minus 4).
