What is the equation of the axis of symmetry for the parabola y=-1/2(x+3)^2-5

Now remember that the vertex's x-coordinate is the same as the axis of symmetry. In this case, looking at the vertex form equation, the vertex's x-coordinate is -3, therefore the equation for the axis of symmetry is x = -3.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.
