graph{y=x^2-5x+4 [-4.494, 7.79, -4.033, 2.107]}

#### Explanation:

$y = {x}^{2} - 5 x + 4$
When x = 1,
$y = 1 - 5 + 4 = 0$
When x = 2,
$y = 4 - 10 + 4 = - 2$
x = 0, y = 4
x = -1, y = 10
x = -2, y = 18
For various values of x, y is calculated and tabled below and plotted in a graph.

| x 5 4 3 2 1 0 -1 -2 -3 -4 -5 |
| y 4 0 -2 -2 0 4 10 18. 28 40 54 |
