Answer:

NO real zeros for this quadratic function.

Explanation:

We can answer this questions looking at the discriminant (
b^2-4ac) associated with this quadratic function:
f(x) =4x^2+2x+6

Discriminant is:
b^2-4ac=(2)^2-4(4)(6)=4-96=-92

Since we get a negative answer, this means that there are NO real solutions to this quadratic function (No real zeros). The zeros are complex numbers.
