Question 62505 • CUSD Math 01 A (5.0)

Which statement best describes the function h(t) = 210 – 15t?

Answer
A
h is the function name; h(t) is the input, or independent variable; and t is the output, or dependent variable.
B
h is the function name; t is the input, or independent variable; and h(t) is the output, or dependent variable.
C
t is the function name; h(t) is the input, or independent variable; and h is the output, or dependent variable.
D
t is the function name; h is the input, or independent variable; and h(t) is the output, or dependent variable.

Explanation

In the notation h(t), h is the function’s name and t is the input, or independent variable. The expression h(t) represents the output, or dependent variable, calculated from that input. So the statement that matches is “h is the function name; t is the input; and h(t) is the output.”
