Question

Y = x² + 6x + 3

What is the vertex?

What is the y-intercept?

Does the parabola open up or down?

Answer 1

Explanation

Vertex (-3,-6)

to find y intercept, let x = 0

y = (0) + 6(0) + 3

y =3

y intercept (0,3)

If x is negative then the graph is upside down, so in this case its open up
