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.

How do you evaluate a function at a specific value?

Back

To evaluate a function at a specific value, substitute the value into the function's equation and simplify.

Front

Given f(x) = -4x - 10, find f(0).

Back

f(0) = -4(0) - 10 = -10.

Front

What does it mean for f(x) = 10?

Back

It means that the output of the function f when the input is x equals 10.

Front

If f(x) = -3(x-1), find f(0).

Back

f(0) = -3(0-1) = 3.

Front

What is the solution to the equation w(x) = 3x - 7 when w(x) = 14?

Back

Set 3x - 7 = 14, then solve for x: 3x = 21, x = 7.

Front

For the function f(x) = -3x + 3, find f(0).

Back

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

Front

What is the output of p(a) = 4a when a = 9?

Back

p(9) = 4(9) = 36.

Front

How do you find the x-value when f(x) = k?

Back

Set the function equal to k and solve for x.

Front

What is the significance of the variable 'x' in function notation?

Back

The variable 'x' represents the input value for the function.
