1) Vero o falso? a. La circonferenza é una linea chiusa La distanza di un punto della circonferenza dal suo cento si chiama raggio. Dae raggi di una circonferenza possono avere lunghezza diverza (ID Tatti ipunti del piano chehanno del centro di una circonferenza distanza minore delt raggio appartengoano allacirconferenza.

Find the real zeros, if any, of the quadratic function using the quadratic formula. What are the \( x \)-intercepts, if any, of the graph of the function? \( f(x)=x^{2}+4 x+1 \) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression. Use a comma to separate answers as needed.) A. The zeros and the x-intercepts are the same. They are B. The zeros and the x-intercepts are different. The zeros are C. There is no real zero solution and no \( x \)-intercepts are
