Find the maximum or minimum of the following quadratic function: y = x^2 - 2x - 4. A. -5 B. -4 C. 5 D. 4
the maximum or minimum occurs at the vertex so you need to find the vertex of this do you know how to find the coordinate of the vertex
Well the x coordinate of the vertex is given by x = -b/2a Once you find the x coordinate, then plug this into the original equation to find the y value which is the maximum value
From my graphing... The minimum = -5
