Activity 1: Draw Me!
Draw the graph of the quadratic function y = x² - 4x +] by following the steps below.
1. Find the vertex and the line of symmetry by expressing the function in the form
-6 b 4ac-b²
y =dx-h) + k or by using the formula h = ik k
if the given quadratic
2a
40
function is in the general form.
2. On one side of the line of symmetry, choose at least one value of x and compute the
value of y
3. Similarly, choose at least one value of r on the other side and compute the
value of V.
4. Plot the points and connect them in a smooth curve.​
