Question

. If you know the number of yards for a measurement, you can change that measure to meters by multiplying the number of yards by 0.9144.

a. Write a function rule that relates meters to yards.

this must be a function

Answer 1

f(y)=0.9144y

Explanation:

We are given that:

1 yard=0.9144 meters

Let y be the number of yards and let f(y) denotes the number of meters corresponding to number of yards y

Then, f(y)=0.9144y

Hence, the function which relates yards to meters is:

f(y)=0.9144y

Answer 2

The correct function would be m(y) = 0.9144y.

Explanation:
Let y be the number of yards and m(y) be the number of meters, dependent upon the number of yards.

We know that we multiply the number of yards, y, by 0.9144; this gives us 0.9144y, which gives us the function

m(y) = 0.9144y.
