What is a piecewise function?

Back

A piecewise function is a function that is defined by different expressions or formulas for different parts of its domain.

How do you evaluate a function at a specific point, such as h(5)?

Back

To evaluate a function at a specific point, substitute the value into the function's equation and simplify.

What does it mean to evaluate f(-5)?

Back

Evaluating f(-5) means substituting -5 into the function's equation and calculating the result.

Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output for each input from its domain.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What is the difference between continuous and discrete functions?

Back

Continuous functions have outputs that can take any value within a range, while discrete functions have outputs that are distinct and separate.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form f(x) = mx + b, where m is the slope and b is the y-intercept.
