Question

Think about the function f(x) = 10 - x^3. What is the input or independent variable?

a. f(x)
b. x
c. y

Answer 1

In the function f(x) = 10 - x^3, the input or independent variable is x, as it is the variable that you can choose freely.

Step-by-step explanation:

In the function f(x) = 10 - x^3, the input or independent variable is b. x. When dealing with functions, the independent variable is typically represented by the letter x, and it is the variable you can choose freely. The outcome of the function, represented as f(x), is the dependent variable because its value depends on what you choose for x. So, in this case, as the question asks for the input or independent variable, the correct answer is b. x.
