Find the x-intercept(s) and vertex for the quadratic function.

f(x)=3x^2-2x-3

Round to the nearest hundredth if necessary.
If there is more than one x-intercept, separate them with commas

Question

Find the x-intercept(s) and vertex for the quadratic function. 

f(x)=3x^2-2x-3

Round to the nearest hundredth if necessary. 
 If there is more than one x-intercept, separate them with commas

luigi0210 · Answer

x-intercept is when y=0
$$\LARGE 0=3x^2-2x-3$$
Factor and solve or use the quadratic formula.

vertex for the trinomial $f(x) = ax^2+bx+c$  is given by $V= (\frac{-b}{2a},f(\frac{-b}{2a}))$

luigi0210 · Answer

Oh, yea vertex formula too^

anonymous · Answer

so, x intercept= 1.39, 0.72?

zzr0ck3r · Answer

I would leave it as the exact answer (fraction).

anonymous · Answer

even though it tells me to round to the nearest hundredth?

zzr0ck3r · Answer

oh disregard that comment then

anonymous · Answer

0.33 for the vertex? @Luigi0210

anonymous · Answer

0.33, -3.33 for the vertex
