The equations of three quadratic functions are: (i) \( y=2 x^{2}+12 x+18 \) (ii) \( y=-3 x^{2}-5 x+3 \) (iii) \( y=x^{2}+2 x-5 \) Determine the discriminant of each function and the number of \( x \)-intercepts that each parabola has. Choose the correct statement. The function described in Select one: a. (ii) has a negative discriminant and the parabola has two \( x \)-intercepts. b. (i) has a zero discriminant and the parabola has one \( x \)-intercept. c. (iii) has a positive discriminant and the parabola has one \( x \)-intercept. d. (i) has no discriminant and the parabola has no \( x \)-intercepts.
