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
[tex]f(c)=t[/tex]
b. If [tex]f(z)=p,[/tex] draw the horizontal line passing through the point (0,p). This line intersects the graph at point K with coordinates (a,p), so [tex]x=a.[/tex]
c. Note that [tex]f(b)=0,[/tex] then
[tex]z=0\\ \\f(z)=f(0)=r[/tex]
d. Coordinates of point L are (c,t), coordinates of point K are (a,p)
