The parabolic equation y = x² - 4x - 1 in the vertex form is y = (x - 2)² - 5 option second is correct.
What is a parabola?
It is defined as the graph of a quadratic function that has something bowl-shaped.
We have a parabolic equation:
y = x² - 4x - 1
y = x² - 2(2)(x) + 2² - 2² - 1
y = (x - 2)² - 4 -1
y = (x - 2)² - 5
Thus, the parabolic equation y = x² - 4x - 1 in the vertex form is y = (x - 2)² - 5 option second is correct.
