Domain, Range, and Is it a Function?

Front

DOMAIN is found by reading the ends of a graph from ___ to ___.

Back

Left to right.

Front

What is the domain of the function represented by the graph?

Back

(-3, 3]

Front

What is the range of the graph?

Back

[-3, 1)

Front

What is the domain of the graph?

Back

(-∞, ∞)

Front

Which graph does NOT pass the vertical line test?

Back

Graph 1

Front

Define 'Domain' in the context of functions.

Back

The set of all possible input values (x-values) for a function.

Front

Define 'Range' in the context of functions.

Back

The set of all possible output values (y-values) for a function.

Front

What is the Vertical Line Test?

Back

A method to determine if a graph represents a function; if a vertical line intersects the graph at more than one point, it is not a function.

Front

What does it mean for a relation to be a function?

Back

Each input (x-value) must correspond to exactly one output (y-value).

Front

Identify the domain of the function f(x) = √(x-1).

Back

[1, ∞) because the expression under the square root must be non-negative.
