Since A‘(-1,1) is on the line y=-x, reflecting it about the line doesn't change its coordinate, so A's coordinate is (-1,1). Reflecting B'(-2,1) about y=-x switches both the sign and the number of x and y, so B=(-1,2), and C'(-1,0) becomes C(0,1). Drawing out the graph with the points and the line helps.
A radius of 0.75 would be rational because the decimal ends and does not repeat itself.
Ok so you would take the bottom which is 15 and divide that by half of 15 which is 7.5. Then you would take the answer (2) and do an equation. You need to put BT at the end. In this case
it’s x = 2 + BT
Using the recursive function given, it is found that f(5) = 6600.
The function given is:
To find f(5), we keep applying the function until 
, hence:
f(2) is f(1) subtracted by 400
f(3) is f(2) subtracted by 400
f(4) is f(3) subtracted by 400
f(5) is f(4) subtracted by 400
Hence, the result is f(5) = 6600.
