Which quadratic function is best represented by this graph? f(x)=x2−6x−8

f(x)=x2+8

f(x)=x2−6x+8

f(x)=x2+6x+8
The graph of a quadratic function with a vertex at negative 3 comma negative 1 and zeros at negative 2 and negative 4

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
