Over what interval is the graph of f(x) = -(x + 8)² – 1 decreasing?
Answer: The graph of f(x) = -(x + 8)² – 1 is always decreasing because it is a downward-opening parabola. Analyzing Quadratic Graphs The graph of a quadratic function y = a(x – h)² + k will open upwards if a is positive and downwards if a is negative. For the function f(x) = -(x […]
