If the point (2,-1)lies on the graph of y=f(x), then a point on the graph of y=f(2x) would be

(1, -1)

Step-by-step explanation:

Since f(2x) is a horizontal compression by factor of 1/2, you multiply the x value of the coordinate by 1/2, so (2, -1) -> (1, -1)

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.

u also answered this so i think u would know but i am here to

put in or use mine
