How to solve this equation 2√4

4

Step-by-step explanation:

First things first we will need to solve the square root.

We can check this by squaring 2.

= 2 x 2 = 4

Now that we have solved the square root, we are left with 2(2). 2 x 2.

2(2) = 4

2 = ?

2(2) = ?

4

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
