They never intersect.
Explanation:
Let's solve the system and see!
#x + 1 = x^2 + 3#
#0 = x^2 - x + 2#
Now we apply the discriminant (the question asks how many solutions, not what they are).
#X = b^2 - 4ac#
#X = (-1)^2 - 4(1)(2)#
#X = -7#
Since
Hopefully this helps!

the answer is no intersect between two equation
Explanation:
because intersect means that ther is same Y between
and
so, lets think
do you under stand?
