Evaluating Functions

Front

Which table represents a function?

Back

A function is a relation where each input has exactly one output. A table represents a function if no two rows have the same input value.

Front

f(x) is the same thing as ______.

Back

y. In function notation, f(x) represents the output value (y) for a given input (x).

Front

If h(x) = -5x + 7, Evaluate h(2).

Back

h(2) = -5(2) + 7 = -10 + 7 = -3.

Front

Which set of ordered pairs is not a function?

Back

A set of ordered pairs is not a function if at least one input value is associated with more than one output value.

Front

What is a function?

Back

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

Front

What is the vertical line test?

Back

The vertical line test is a method to determine if a curve is a function. If a vertical line intersects the curve at more than one point, it is not a function.

Front

What does the domain of a function represent?

Back

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

Front

What does the range of a function represent?

Back

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

Front

How do you evaluate a function at a specific point?

Back

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

Front

What is a linear function?

Back

A linear function is a function that can be graphically represented as a straight line, typically in the form f(x) = mx + b.
