How do I find the vertex of the equation y= (x+7)^2 - 5 ?
Follow through with the function (x+7)² (x+7)² is the same as (x+7)(x+7). You get x² + 14x + 49 Plug it back into the equation to get y=x² + 14x + 49 - 5, which equals y=x² + 14x + 44 The formula for the x point in the vertex is -b/2a. (a is x² and b is x) So -14/2 = -7 = x Plug this into the equation. y=-7² + 14(-7) + 44 y=49 - 98 + 44 y=-5
(-7, -5)
I apologize for the error beforehand--I typed 49 instead of 44 and ended up with 0 instead of -5.
