Graph the Quadratic functions in a Graphing Paper.
f(x)=ײ-3×+4
[tex]\[\begin{array}{l}y = {x^2} - 3x + 4\\\\y = ({x^2} - 3x + {(\frac{3}{2})^2}) + 4 - {(\frac{3}{2})^2}\\\\y = ({x^2} - 3x + \frac{9}{4}) + 4 - \frac{9}{4}\\\\y = {(x - \frac{3}{2})^2} + \frac{7}{4}\\\\vertex(\frac{3}{2},\frac{7}{4})\end{array}\][/tex]
if x = 0
y = x² - 3x + 4
y = 0² - 3(0) + 4
y = 4
y intercept (0, 4)
