Question

Given the function, d(t) = 50t, the variable t represents which of the following?

Select all that apply.

dependent variable
input
function
independent variable
output

Answer 1

Given the function \( d(t) = 50t \), the variable \( t \) represents the following:

- **Input**: \( t \) is the value we provide to the function to calculate \( d(t) \).
- **Independent variable**: \( t \) is independent because it can take any value, and it determines the value of \( d(t) \).

The other options do not apply to \( t \):

- **Dependent variable**: This would be \( d(t) \) since its value depends on \( t \).
- **Function**: The function itself is \( d(t) \), not \( t \).
- **Output**: This also refers to \( d(t) \), as it is the output of the function when \( t \) is input.

Therefore, the correct answers are **input** and **independent variable**.
