Question

think about the function $f(x) = 10 - x^3$. what is the input, or independent variable? $\circ$ $f(x)$ $\circ$ $x$ $\circ$ $y$

Explanation:

In a function of the form \( f(x) \), the independent variable (input) is the variable that we can choose values for, and the function's output depends on it. Here, \( f(x)=10 - x^{3} \), so \( x \) is the independent variable (input), \( f(x) \) is the output (dependent variable), and \( y \) isn't part of the function's definition here.

Answer:

B. \( x \)
