Question

A yard is equal in length to three feet. The function f(x) takes a measurement in yards (as input) and returns a measurement in feet (as output). What number will the function return if the input is 10.5?

Answer 1

Answer: 31.5

Step-by-step explanation:

Given: A yard is equal in length to three feet.

The function f(x) takes a measurement in yards (as input) and returns a measurement in feet (as output).

$\\\Rightarrow\ f(x)=3x$

If input = 10.5

Then $f(10.5)=3(10.5)$

$\Rightarrow\ f(10.5)=31.5$

Hence, 31.5 is the number will the function return if the input is 10.5.

Answer 2

If it takes yards and turns it into feet then it just multiplies it by 3

so if the input is 10.5 then you just multiply it by three

31.5 feet is the imput
