Answer:
a. t
b. a (or x = a)
c. r
d.
1) c
2) t
3) a
4) p
Step-by-step explanation:
a. Draw vertical line passing through the point (c,0). This line intersects the graph at point L. Point L has coordinates (c,t), so

b. If
draw the horizontal line passing through the point (0,p). This line intersects the graph at point K with coordinates (a,p), so 
c. Note that
then

d. Coordinates of point L are (c,t), coordinates of point K are (a,p)
Answer:
90°
Step-by-step explanation:
angle of rotation=90°
Answer:
-1280.
Step-by-step explanation:
f(n + 1) = -2 f(n):
As function of 1 = 160, function of 2 = -2 * 160 = -320.
function of 3 = -320 * -2 = 640 and
= function of 4 = 640 * -2 = -1280.
