Question

Find the vertex of the parabola and indicate if it is a minimum or maximum for the function
f(x) = -5(x + 6)2 - 5

Answer 1

Your equation is in vertex form
y = a(x-h)^2 + k
(h,k) are your vertex coordinates.

Answer 2

minimum or maximum? How can I tell?

Answer 3

a < 0
so the graph as a minimum of -5

Answer 4

if a > 0
then the graph has a maximum

Answer 5

it occurs when x = - 6

Answer 6

so its a minimum?

Answer 7

Oh oops, I did the wrong way.
if a > 0 its a minimum
if a < 0 its a maximum
sorry. i mixed them up.

Answer 8

it s maximum when x = -6
