Front

Using the graph, find f(-3) if f(x) = -3 for x = -3.

Back

f(-3) = -3.

Front

What is the equation of the piecewise function for x ≥ 3?

Back

The equation is -1 if x ≥ 3.

Front

What does the interval notation (-∞, 5] represent?

Back

x ≤ 5.

Front

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

Back

The domain is (-∞, +∞).

Front

What is a piecewise function?

Back

A function defined by multiple sub-functions, each applying to a certain interval.

Front

How do you find the value of a function at a specific point?

Back

Substitute the specific point into the function's equation.

Front

What is the range of a function?

Back

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

Front

What is the difference between domain and range?

Back

Domain refers to input values (x-values), while range refers to output values (y-values).

Front

What does the notation f(x) mean?

Back

f(x) represents the output of the function f for the input x.
