This graph represents a quadratic equation that will have:
Options:

2 imaginary roots

,

2 real roots

,

1 real root and 1 imaginary root

Back

2 imaginary roots

Answer explanation

Since the graph doesn't cross the x-axis, no value of x will make the equation equal zero. Thus, the equation has two imaginary roots.
