How do you find the intercepts, vertex and graph #f(x)=3x^2+6x-1#?
1 Answer
y-int
x-int
vertex
Explanation:
to find the intercepts
∙
let x = 0, in the equation for y-intercept
∙
let y = 0, in the equation for x-intercepts
since this equation is not factorable, use uadratic fomula to solve for
a=3
b=6
c=-1
answer:
for parabola
plug in -1 to find y value
vertex is
