Question 37494
For the function f(x)= -x^2-6x-8
=-{X^2+2*X*3+3^2}+9-8
=1-(X+3)^2

(a) Find the line of symmetry
X+3=0 IS LINE OF SYMMETRY
(b) State whether there is a minimum or a maximum and find that value
SINCE MINIMUM VALUE OF -(X+3)^ IS 0,WE GET A MAXIMUM FOR F(X) AT THIS POINT IT IS 
F(X)=1-0=1 

(c) Find the range
 F(X) CAN TAKE ANY VALUE FROM MAXIMUM =1 TO MINUS INFINITY
