Please help me find the AXIS OF SYMMETRY for this...

y= -5xsquared-10x

To find the axis of symmetry for a quadratic equation in the form of y = ax^2 + bx + c, you can use the formula x = -b / (2a).

In your equation y = -5x^2 - 10x, we can see that a = -5 and b = -10.

Now, substitute these values into the formula x = -b / (2a):

x = -(-10) / (2 * -5)
x = 10 / -10
x = -1

Therefore, the axis of symmetry for the given quadratic equation is x = -1.
