Expert Solution

## Answer to Problem 44RE

The last equation is a rule that gives one value of y for each value of x ,

So it defines y as a function of x .

### Explanation of Solution

Given information: consider the equation 2x=y416

Calculation:

Now solve y in terms of x gives,

y4=2x+16y2x+164

The last equation is a rule that gives one value of y for each value of x ,

So it defines y as a function of x .

Thus, write the function as f(x)=2x+164
