Question

Find the vertex , the line of symmetry, and the max or min value graph the function
F(X)=1/3(x+7)^2+1

Answer 1

vertex = (-7, 1)

So the line of symm will be,
x= -7

It will be a min point since the value if "a" is +.
Answer for 3rd = 1

Answer 2

First find the first derivative then substitute the x-value in to find the stationary points. Then find the second derivative to determine its nature-either max or min,

Answer 3

i like the calculus method, much for elegant

Answer 4

The calculus method is much more easier.
