Quadratic Functions
Consider the Quadratic Function f(x)=x2−4x+3\displaystyle {f{{\left({x}\right)}}}={x}^{{2}}-{4}{x}+{3}
1) Does the graph open up or down and why?:

f(x)=x2−4x+3\displaystyle {f{{\left({x}\right)}}}={x}^{{2}}-{4}{x}+{3}

2) Write the Vertical Intercept as an Ordered Pair

3) Write the Vertex as an Ordered Pair

5) Determine the Domain of f(x)=x2−4x+3\displaystyle {f{{\left({x}\right)}}}={x}^{{2}}-{4}{x}+{3}.
Write your answer in interval notation.
6) Determine the Range of f(x)=x2−4x+3\displaystyle {f{{\left({x}\right)}}}={x}^{{2}}-{4}{x}+{3}.
Write your answer in interval notation.
