Answer:
D
Step-by-step explanation:
f(x) * g(x)= (3x^2-4x-5)(11x-3)
33x^3-44x^2-55x-9x^2+12x+15
33x^3-53x^2-43x+15
For this case, we have to define perpendicular lines:

We have then:

Then, according to the definition we have:

We observe that the definition is fulfilled, therefore, the lines are perpendicular.
