Final answer:
The equation y2=3x+1 is a function.
Step-by-step explanation:
Determine whether y2=3x+1 is a function
A function is a relation in which each input has exactly one output. To determine if the equation y2=3x+1 is a function, we need to check if each input value of x corresponds to exactly one output value of y.
In this case, the equation represents a quadratic curve, which passes the vertical line test, meaning that it is indeed a function.
For example, when x=1, we can substitute it into the equation as follows: y2 = 3(1) + 1 = 4.
Therefore, for every value of x, there is a unique value of y, indicating that the equation y2=3x+1 is a function.
