The graph of y = -2(x - 6)² has been attached.
How to graph quadratic function?
A quadratic function refers to a function whose value is the solution of a quadratic polynomial.
y = -2(x - 6)²
y = -2(x - 6)(x - 6)
y = -2(x² - 6x - 6x + 36)
y = -2(x² - 12x + 36)
y = -2x² + 24x - 72
x = 6
From the attached graph, the solution of the quadratic function is 6
Therefore, x equals 6
