SOLUTION: For the following function, tell where the function is increasing and decreasing. What is the concavity? Give the coordinates of the vertex and the equation of the axis of symmetry

Question 111500: For the following function, tell where the function is increasing and decreasing. What is the concavity? Give the coordinates of the vertex and the equation of the axis of symmetry. f(x)= -3(x+2)^2+3
Answer by checkley71(8403) (Show Source): You can put this solution on YOUR website!
f(x)=-3(x+2)^2+3
f(x)=-3(x^2+4x+4)+3
f(x)=-3x^2-12x-12+3
f(x)=-3x^2-12x-9
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, y = -3x^2 -12x -9).
----------------------------------------------------------------
curve is decreasing.
vertex is (-2,3)
symetry is x=-2
