Consider $y = x^{2} - 5 x + 4$
Graph the function.

Short Answer

Expert verified

The graph of the function $y = x^{2} - 5 x + 4$ is given below.

Step by step solution

Step 1. Define the standard form of the quadratic function.

A quadratic function, which is written in the form, $y = a x^{2} + b x + c$ , where, $a \neq 0$ is called the standard form of the quadratic function.

Step 2. Calculate the table of values for the function y=x2−5x+4.

$x$	$y$
$- 1$	10
0	4
1	0
2	$- 2$
3	$- 2$

Step 3. Use the table of values to graph the function y=x2−5x+4.

Graph the ordered pairs from the table and connect them to create a smooth curve.

This is the required graph of the function $y = x^{2} - 5 x + 4$ .
