U4L3 - Function Notation Practice

Front

What is function notation?

Back

Function notation is a way to represent functions in mathematics, typically using symbols like f(x) to denote the output of a 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 expression and simplify.

Front

What does f(2) represent in function notation?

Back

f(2) represents the output of the function f when the input is 2.

Front

If f(x) = 3x + 1, what is f(2)?

Back

f(2) = 3(2) + 1 = 7.

Front

What is the significance of the graph of a function?

Back

The graph of a function visually represents the relationship between the input values (x-axis) and the output values (y-axis) of the function.

Front

How can you find the value of a function from its graph?

Back

To find the value of a function from its graph, locate the input value on the x-axis, then find the corresponding output value on the y-axis.

Front

What does h(-1) indicate?

Back

h(-1) indicates the output of the function h when the input is -1.

Front

If f(4) = 3, what does this tell you about the function f?

Back

This tells you that when the input to the function f is 4, the output is 3.

Front

What is the output of a function if f(8) = -2?

Back

The output of the function f when the input is 8 is -2.

Front

What is the difference between f(x) and g(x)?

Back

f(x) and g(x) can represent different functions, each with its own set of rules and outputs for given inputs.
