4. Determine los componentes de la función cuadrática y grafique. \( -x^{2}+4 x-1=0 \quad a=-x^{2} \quad b=4 \times \quad c=1 \) - Concavidad: \( a>a \) - Eje simetria \( x=2 \) - Vértice: \( (a, 3) \) - Intersecciones eje \( x: x=2+\sqrt{3} \) - Intersección eje y:

verify \( (0,2) \) and \( (-2,3) \) are solution of \( x+2 y=4 \)

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 different. The zeros are B. The zeros and the x-intercepts are the same. They are C. There is no real zero solution and no \( x \)-intercept.
