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

Evaluate f(x) = 2x² + 5x - 3 at x = 4.

Back

f(4) = 2(4)² + 5(4) - 3 = 32 + 20 - 3 = 49.

Front

Evaluate f(x) = 2x² + 5x - 3 at x = 2.

Back

f(2) = 2(2)² + 5(2) - 3 = 8 + 10 - 3 = 15.

Front

Evaluate f(x) = 2x² + 5x - 3 at x = 6.

Back

f(6) = 2(6)² + 5(6) - 3 = 72 + 30 - 3 = 99.

What is a function?

Back

A function is a relation that assigns exactly one output value for each input value.

Front

What does it mean if a mapping is 'Not a Function'?

Back

A mapping is 'Not a Function' if at least one input value is associated with more than one output value.

Front

How do you find 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 a function and a relation?

Back

A function is a specific type of relation where each input is related to exactly one output.

Front

What is the significance of evaluating a function?

Back

Evaluating a function allows us to find the output value for a given input, which is essential for understanding the behavior of the function.

What is the standard form of a quadratic function?

Back

The standard form of a quadratic function is f(x) = ax² + bx + c, where a, b, and c are constants.
