Make y the subject of the formula

C

Step-by-step explanation:

w=x^2 - 2yz

w/-2z = x^2 + y

x^2 - w/2z = y

C. Both f(x) and g(x)

Step-by-step explanation:

We are given,

Graphs of three function namely f(x), g(x) and p(x).

It is require to find the functions having the set of real numbers as the domain.

From the graph, we have,

The domain of the function p(x) is a subset of [-2,2] and is not the set of all real numbers.

Whereas, the domain of the functions f(x) and g(x) is the set of all real numbers.

Hence, option C is correct.
