I'm assuming y =–x2+3 means y=x²+3 They are asking.. if the two equations equal each other how many solutions are there? x²+3 = x+1 Put it all on one side: 0=x+1+x²3 0=x²+x2 x²+x2=0 Solve the quadratic by factoring: (x1)(x+2)=0 So x=1 or x=2 Answer: Two times at x=1 and again at x=2.

Wait, you shouldn't have three solutions... because that would imply that the function x + 1  x^2 + 3 had three zeros which can't happen by the fundamental theorem of algebra
