Question

The function g(x) = 10x2 – 100x + 213 written in vertex form is g(x) = 10(x – 5)2 – 37. Which statements are true about g(x)? Check all that apply.
The axis of symmetry is the line x = –5.


The vertex of the graph is (5, –37).


The parabola has a minimum.


The parabola opens up.


The value of a, when the equation is written in vertex form, is negative

Answer 1

Axis of symmetry is the X pair of the vertex

Answer 2

in the formula of vertex: \[a^2+(x-h)^2+k\]

Answer 3

So h is the axis of symmetry,

Answer 4

-(5)

Answer 5

The axis of symmetry is 5.
