Question

True or false? The graph represents a function. A.True B.False

Answer 1

answer:

false

explanation:

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.

functions can have multiple x-intercepts but only ONE y-intercept.

Answer 2

By definition, a function is an equation where any input, a value of x, has exactly one and only one output, a value of y. Since we see the same x value have multiple y-values in this equation, this is not a function.
