Find the vertex using the vertex formula.

Question

h(x)=x²+6x-7

 

The Vertex is:_______

The Axis of Symmetry is: _____________

The Min/Max Value is:______________

The x-intercept(s) is, if they exist:____________

The y-intercept is:_________________

Answer 1

h(x) = x² + 6x - 7

h(x) = x² + 6x + 9 - 7 - 9        completion of the square

h(x) = (x + 3)² - 16

 

This is vertex form.
