Step-by-step explanation:

Answer 2

Answer:

The value of f(4) is equal to 123.

Step-by-step explanation:

We have given the expression:

           $f(w)=2w^{3}-5$                        .............(1)

To find the value of f(4):

Put $w=4$ in eq. (1),

We get     $f(4)=2(4)^{3}-5\\ f(4)=128-5\\ f(4)=123$
