Answer:

NO real zeros for this quadratic function.

Step-by-step explanation:

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

Discriminant is:  [tex]b^2-4ac=(2)^2-4(4)(6)=4-96=-92[/tex]

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.
