Question

Identifying Input and Output
Which statement best describes the function h(t) = 210 – 15t?

h is the function name; h(t) is the input, or independent variable; and t is the output, or dependent variable.
h is the function name; t is the input, or independent variable; and h(t) is the output, or dependent variable.
t is the function name; h(t) is the input, or independent variable; and h is the output, or dependent variable.
t is the function name; h is the input, or independent variable; and h(t) is the output, or dependent variable.

Answer 1

Correct answer:
h is the function name; t is the input, or independent variable; and h(t) is the output, or dependent variable.

Explanation: In h(t)=210−15t, h denotes the function, t is the input variable, and h(t) is the value (output) of the function for that input.
