Step-by-step explanation:

P.S - The exact question is -

Given - Function w gives the weight of a cat, in kilograms, when it is

To find - Which statement represents the meaning of the equation

               w(7) = 4 in this situation?

              A) The cat weighs 7 kilograms when it is 4 months old.

Proof -

Given that,

Function w gives the weight of a cat , in kilograms, when it is m months old.

So, the function is represented as

w(x) = y

It means

The weight of the cat is y kilograms when she is x months old.

Now,

Given the function is w(7) = 4

Put x = 7 , y = 4 , we get

The weight of the cat is 4 kilograms when she is 7 months old.

So,

The correct option is - B) The cat weighs 4 kilograms when it is 7 months old.
