Quadratic Functions
Consider the Quadratic Function f(x)=−x2+2x−5\displaystyle {f{{\left({x}\right)}}}=-{x}^{{2}}+{2}{x}-{5}
1) Does the graph open up or down and why?:

f(x)=−x2+2x−5\displaystyle {f{{\left({x}\right)}}}=-{x}^{{2}}+{2}{x}-{5}

12345678-1-2-3-4-5-6-7-812345678-1-2-3-4-5-6-7-8xf(x)
2) Write the Vertical Intercept as an Ordered Pair
