Question

What is the vertex of the graph of y = −3x2 − 2x + 1?

Answer 1

thanks

Answer 2

@jpw, do you know how to find the vertex of the graph algebraically?

Answer 3

no i need help

Answer 4

no sorry

Answer 5

The vertex of the quadratic function is \(\left(-\frac{b}{2a}\right), f\left(-\frac{b}{2a}\right)\)

Answer 6

so how`would i plug the numbers in

Answer 7

You can do that, or you can convert the equation to vertex form

y = a(x - h) + k where (h , k) is the vertex.

Answer 8

a = -3, b = -2 c = 1

Answer 9

i like the first one better

Answer 10

so it would be 2 divided by 9?
