Question

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

The statement which best describes the function h(t) is:

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

Explanation:

We know that for any function:

f(t) t is the input or the independent variable and the function f(t) itself is the output obtained corresponding to each value of the input.

i.e. f(t) is the dependent variable since it depends on the variable t.

Here we have a function h(t) as:

`h(t)=210-15t`

so, t here is the independent variable.

and h(t) is the dependent variable or the output.

( since on putting the value of t we get the value of the function)

Also, h is the function name.

Answer 2

The second choice is the best description:

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