Final answer:
The equations y2 = 3x + 3, y3 = 2 + 3, and y = ° + 3 are analyzed to determine if they are functions.
Step-by-step explanation:
The equations provided are y2 = 3x + 3, y3 = 2 + 3, and y = ° + 3.
To determine if they are functions, we need to check if each x-value (independent variable) in the equation corresponds to only one y-value (dependent variable).
For the equation y2 = 3x + 3, it represents a linear equation and is a function since each x-value will produce a unique y-value.
However, y3 = 2 + 3 and y = ° + 3 are not functions because there is no explicit representation of the independent variable x. In the first equation, y is a constant. In the second equation, there is no relation between x and y.
Therefore, the correct answer is (b) Only y2 = 3x + 3 is a function.
