f is a trigonometric function of the form f(x)=acos(bx+c)+d. Below is the graph of f(x). The function has a maximum point at (pi,6) and a minimum point at (−3π/4 ,2). Find a formula for f(x). Give an exact expression.

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

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.

the answer is z7+8/5
