Find The $x$ And $y$ Intercepts $x$ Intercepts Exist, State So $f(x)=-3 x^{2}+9 x+20$

Multiple Choice

Find the $x$ and $y$ intercepts. If no $x$ intercepts exist, state so.
- $f(x) =-3 x^{2}+9 x+20$

A) No $x$ -intercepts; $y$ -intercept: -20
B) No $x$ -intercepts; $y$ -intercept: 20
C) x-intercepts: $\frac{-9 \pm \sqrt{321}}{2}$ ; -intercept: -20
D) $x$ -intercepts: $\frac{-9 \pm \sqrt{321}}{2} ; y$ -intercept: 20
