Integrate the function listed above and substitude the coordinates (-3,0) into the result. You will be able to find the equation of the curve. Hope it helps.
thank you got it my math was wrong
What is the actual answer to this..I am upset that somethings so simple stumped me for a minute.
dy/dx = 2x+1
y = x^2 + x + c ( after integration )
0 = (-3)^2 + (-3) + c ( now substitute x = -3 and y=0 to find c )
c = 6 should be -6
therefore the equation is, y = x^2 + x - 6 (ans)

no the answer is
Sorry minor calculation error. Thread updated.
i did the same thing at first too
It is common to make careless mistakes in mathematics that's the reason we have to double check the equations again to prevent any careless mistakes from happening.
