How to graph y = x^2 - 5x + 4
Explanation:
Here are the important parts to graph the quadratic function:
x-coordinate of vertex:
y-coordinate of vertex:
y-intercept--> Make x = 0 --> y = 4
x-intercepts --> make y = 0 --> solve
Since (a + b = c = 0), use the Shortcut. The 2 real roots are:
x = 1 and
graph{x^2 -5x + 4 [-10, 10, -5, 5]}
