Function Notation

Front

What is function notation?

Back

Function notation is a way to represent a function using symbols. It typically uses the format f(x), where 'f' is the name of the function and 'x' is the input variable.

If f(x) = 5x - 25, what is x if f(x) = 10?

Back

x = 7

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 input variable into the function's equation.

Front

Given f(x) = -2x + 10, find f(-3).

Back

f(-3) = 16

Front

If f(x) = 20 - 1.5x, evaluate f(6).

Back

f(6) = 11

Front

What does f(2) = 5 indicate about the input and output?

Back

It indicates that when the input is 2, the output of the function is 5.

Front

What is the independent variable in a function?

Back

The independent variable is the input variable, often represented as 'x' in function notation.

Front

What is the dependent variable in a function?

Back

The dependent variable is the output of the function, often represented as 'f(x)'.

Front

How do you find the output of a function for a given input?

Back

Substitute the input value into the function's equation and simplify to find the output.

Front

What is the significance of the function's name in function notation?

Back

The function's name (e.g., f, g, h) identifies the specific function being referred to.
