`y=3`
`y=ax^(2)+b`
In the system of equations above, a and b are constants. For which of the following values of a and b does the system of equations have exactly two real solutions?

Options

A. a = −2, b = 2
B. a = −2, b = 4
C. a = 2, b = 4
D. a = 4, b = 3

Explanation

To solve the problem, we need to determine the values of \( a \) and \( b \) such that the system of equations:

1. \( y = 3 \)
2. \( y = ax^2 + b \)

has exactly two real solutions.
