Question

Y= -(x+3)^2 -5 What is the leading coefficient? How do you find the vertex?

Answer 1

Answer:

To find the leading coefficient, first expand the function:

$y= -(x+3)^{2} -5\\\\y=-(x^{2} +6x+9)-5\\\\y=-x^{2} -6x-9-5\\\\y=-x^{2} -6x-14$

The leading coefficient is the coefficient of the highest-order term, which, in this case, would be the -1 from -x².

To find the vertex: see image below

Vertex = (-3, -5)
