Match each equation with the diagram it represents.pls help

Oh this is actually pretty easy I think, I hope I get this right! So, Im pretty sure the first one goes to diagram C. The second one goes to diagram D. And I think the third one goes to diagram B. And the last one goes to diagram A. Please dont hate me if I am wrong! Sorry if I am though!

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
