Question

The weights and heights of six mathematics students are given in the following table:

Weight (in pounds)
Height (in centimeters)
165
172
123
157
212
183
175
178
165
163
147
167

In the statement, "Height is a function of weight," which variable is the input and which is the output?
a.
Weight is output, height is input
b.
Both weight and height are the input
c.
Weight is input, height is output
d.
Both weight and height are the output

Answer 1

c. Weight is input, height is output

Explanation:

It is given here that "Height is a function of Weight".

which means

`Height = f(Weight)`

Thus, value of Height is depend on the value of Weight.

Thus, Weight is input variable and Height is output variable.

Hence option (c) is correct.

Further,

The variable that we can change is called the Input variable.

The Output variable depends upon the input variable, as we change the value of the input variable the value of the output variable is also get changed.
