What is the y-intercept, axis of symmetry and vertex of the following function? F(x)=-3x^(2) -6x-5

Question

What is the y-intercept, axis of symmetry and vertex of the following function?


`F(x)=-3x^(2) -6x-5`

Answer 1

Y-Intercept: -5

Axis of symmetry: -1

Vertex: (-1,-2)

Explanation:

Y- intercept is is always the number without a variable

Axis of symmetry is the x cordirant of the vertex

Vertex: You can turn the equation into vertex form

(photo example below) (IMPORTANT: once you turn your equation into vertex form, remember that the number inside the prencencys has to be turned to the opposite sign (-/+) when you put it as a coordinate)
