Question

What would a parabola's points be for the equation: Y=x^2+4x+1 When the values start at -5?

Answer 1

okay can by point you mean the vertex?

Answer 2

The vertex will be one of them...

Answer 3

and "values start at -5". that's for the domain?

Answer 4

I'm guessing so, that's all the instructions tell me.

Answer 5

okay.

Answer 6

+
\
now vertex of a standard parabola ax^2 + bx +c

is (-b/2a . -D/4a)

where D is the discriminant \[D = \sqrt{b^2 - 4ac}\]

compare the equation of your parabola with that of this std. parabola, get , b, c

a=1
b=4
c=1

so plug the values, and get the vertex!
