I stumbled upon this problem and I was looking at the solution, but I think the answer is actually 3 points because if you plug in 2 to the second equation, it makes the equation 0 so it also works. I am just asking to see if my understanding is correct or if I missed something, thanks.
+738 hmmm I think CPhill is correct...
If you plug in 2 to the second equation, you get: \(2^2+3(2)-38=4+6-38=\boxed{-28}\)
And \(-28 \neq 2\)

The graph of the function is in red, and the function has a value of 2 at only two points.
(The red function intersects the green line at only two points.)
