What is the axis of symmetry of the function f(x)=−(x+9)(x−21)?ymmetry of the function f(x)=−(x+9)(x−21)?

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
