Question

Find its vertex its x- and y-intercept(s). (If an answer does not exist, put DNE)

f(x)=3x^2+6x-1

Answer 1

I got the Y-intercept, which is (0,-1).

Answer 2

Need the smaller and larger values of the X-intercept.

Answer 3

y-1+3=3(x^2+2x+1) ===> (y+2)=3(x+1)^2 ===> vertex =(-1,-2) ,,, y- intercept is y=1 ,
