Evaluate Functions from graphs, tables, mapping diagrams

Front

What is a function in mathematics?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

What does f(x) represent in a function?

Back

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

Front

How do you evaluate a function at a specific point?

Back

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

Front

What is the significance of the x-value in a function?

Back

The x-value is the input to the function, which determines the corresponding output (y-value) based on the function's rule.

Front

What does it mean to find h(-3) in a function h?

Back

Finding h(-3) means to evaluate the function h at the input value of -3 to determine the corresponding output.

Front

How can you interpret f(x) = 12 in terms of x?

Back

The equation f(x) = 12 indicates that the output of the function f is 12; to find x, you need to determine which input gives that output.

Front

What is the output of a function when x = 3 if f(3) = 7?

Back

The output of the function when x = 3 is 7.

Front

How do you find the output of a function at x = -1?

Back

To find the output of a function at x = -1, substitute -1 into the function's equation and solve for the output.

Front

What does it mean if h(0) = 15?

Back

If h(0) = 15, it means that when the input to the function h is 0, the output is 15.

Front

What is a mapping diagram?

Back

A mapping diagram visually represents the relationship between inputs and outputs of a function, showing how each input is paired with its corresponding output.
