Given the quadratic function, to get the roots we factorize:
3x²-4x-7=0
3x²+3x-7x-7=0
3x(x+1)-7(x+1)=0
(3x-7)(x+1)=0
thus the roots are
x=-1 or x=3/7
thus the sum of the roots will be:
-1+3/7
=-4/7

Answer:
Step-by-step explanation:
-12 goes on the x axis (the line that goes ⇄), and because it's negative, it will go to the right.
start from that point (-12 on the x axis) and start going down till you reach -52 on the y axis (the line that goes ⇅)
so it should end up in the bottom left part of the graph
