True or false: The equation y=−3

Question

𝑦
=
−
3
is a function. Enter 1 for true or 2 for false.

Answer 1

The equation $y=-3$ represents a horizontal line where the value of $y$ is always -3, regardless of the value of $x$.

In the context of functions, for an equation to be a function, each input (or $x$-value) must correspond to exactly one output (or $y$-value). In this case, every value of $x$ gives a single output of -3, which meets the criteria for being a function.

Therefore, the statement is true.

Enter: 1.
