Determine the maximum possible number of turning points for the graph of the function f(x)=-x^2-6x-7

To find the maximum possible number of turning points for the graph of the function f(x) = -x^2 - 6x - 7, we need to analyze the degree of the polynomial.

The given function is a quadratic function (degree 2) because the highest power of x is x^2.

A quadratic function can have a maximum of one turning point.

Therefore, the maximum possible number of turning points for the graph of f(x) = -x^2 - 6x - 7 is 1.
