Step-by-step explanation

Since we have the function:


f(x)=3x^2+12x-5

The discriminant of the quadratic is given by the following expression:


b^2-4ac

Where a=3, b=12 and c=-5:

Plugging in the terms into the expression:


12^2-4*3*(-5)

Multiplying terms:


144+60

Adding numbers:


Discriminant=204

In conclusion, since the discriminant is >0 , the appropriate option is OPTION A.
