Function Notation

Front

What is function notation?

Back

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

Front

What does f(1) represent?

Back

f(1) represents the output of the function f when the input is 1.

How do you convert an equation like y = 2x - 3 into function notation?

Back

You write it as f(x) = 2x - 3.

Front

What is the first step to evaluate f(1) if f(x) = 2x + 1?

Back

Plug a 1 in for all the x's.

Front

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

Back

f(1) = 3.

Front

What is the output of f(x) if f(x) = -2?

Back

To find x when f(x) = -2, you need to solve the equation for x.

Front

What does it mean if a function is linear?

Back

A linear function is a function that graphs to a straight line, typically in the form f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

What is the slope in the function f(x) = 2x - 3?

Back

The slope is 2.

Front

What is the y-intercept in the function f(x) = 2x - 3?

Back

The y-intercept is -3.

Front

How do you find the value of x if f(x) = 0?

Back

Set the function equal to 0 and solve for x.
