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.

What does f(1) = 5 mean?

Back

It means that when the input to the function f is 1, the output is 5.

Front

How do you find the value of x if f(x) = -2?

Back

You need to determine which input x gives an output of -2 when substituted into the function f.

Front

What does it mean to find f(x) when f(x) = 0?

Back

It means you are looking for the input x that makes the output of the function f equal to zero.

Front

If f(8) = -2, what does this indicate?

Back

This indicates that when the input to the function f is 8, the output is -2.

Front

What is the significance of finding f(-3)?

Back

Finding f(-3) means you are determining the output of the function f when the input is -3.

Front

What is the general form of a linear function?

Back

The general form of a linear function is f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

What is the slope of a function?

Back

The slope of a function represents the rate of change of the function's output with respect to its input.

Front

What is a zero of a function?

Back

A zero of a function is an input value x for which the output f(x) equals zero.

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.
