Answer:
Hello dear asker, you have to put the picture of the graph, then I would be happy to help
The ones with a square in a picture is a 90 degree angle the rest are a 180
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
