W(x) = 0.35x Since body weight x is positive and if it increases then W(x) also increase. Domain is (0, ∞) i.e.,x > 0

\displaystyle \sf{  The  \: domain \:  of \:  the \:  function \:  is  \bf \:  \: (0, \infty ) }

Given :

The weight of the muscle of a man is a function of his body weight x and can be expressed as W(x) = 0.35x

To find :

The domain of the function

Solution :

Step 1 of 2 :

Write down the given function

Here it is given that the weight of the muscle of a man is a function of his body weight x and can be expressed as W(x) = 0.35x

Step 2 of 2 :

Find domain of the function

Here x is the body weight of the man

Now weight of the man can be any real number

∴ x ∈ R

Again x is always positive

∴ x > 0

Hence domain of the function

 \sf = \{ \:  x \in \:R  : 0 < x <  \infty  \}

\displaystyle \sf{ = (0, \infty )  }
