Front

What are all of the y values or outputs called?

Back

Range

Front

What is the domain of the graph?

Back

All real numbers

Front

What is the range of the graph?

Back

y≥1

Front

What are all of the x values or inputs called?

Back

Domain

Front

What is the domain?

Back

−∞ < x < ∞

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

If a function has a domain of x ≥ 0, what does this mean?

Back

The function accepts all x-values that are 0 or greater.

Front

If a function has a range of y < 5, what does this mean?

Back

The function outputs values that are less than 5.

Front

What is the domain of the function f(x) = √x?

Back

x ≥ 0
