Solve for x. 2x2 − 4x = 0 a. 0, -4 b. 0, -2 c. 0, 2 d. 2, 4

C) 0, 2

Step-by-step explanation:

Given  : 2x² − 4x = 0.

To find : Solve for x.

Solution : We have given

2x² − 4x = 0.

On taking 2x common .

2x ( x - 2 ) = 0.

For 2x  = 0 .

On dividing both sides by 2

x = 0.

For x -2 = 0 .

On adding both sides by 2 .

x = 2 .

Solution are 0 , 2 .

Therefore, C) 0, 2

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.
