Function Notation

Front

What is function notation?

Back

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

What does f(8) represent in function notation?

Back

f(8) represents the output of the function f when the input is 8.

Front

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

Back

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

Front

What does h(4) = 5 mean in the context of a function?

Back

It means that after 4 weeks, the height of the plant is 5 inches.

Front

How do you express the equation y = 2x - 3 in function notation?

Back

f(x) = 2x - 3.

Front

What is the output of the function f(x) = x^2 when x = -3?

Back

f(-3) = (-3)^2 = 9.

Front

What is the relationship between f(x) and y?

Back

f(x) is another way to express y, where y is the output of the function for a given input x.

Front

If f(x) = 3x - 4, what is f(0)?

Back

f(0) = 3(0) - 4 = -4.

Front

What does it mean if f(a) = b?

Back

It means that when the input is a, the output of the function f is b.

Front

How do you find the value of f(-1) if f(x) = 2x^2 + 5x - 17?

Back

f(-1) = 2(-1)^2 + 5(-1) - 17 = -20.
