The quadratic function f(x) has a turning point at (-3, 8). If the function g is defined by g(x) = -f(x + 5) for all values of x then at which of the following points will g(x) have a turning point?

step-by-step explanation:

ab will be equal to

126 maybe. sorry

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.
