急! F5 Graphs of Functions 3q3

(a)
(i)
Transformation: upward translation of 10 units.

(ii)
y = (x-3)^3
Transformation: rightward translation of 3 units.
y = (x-3)^3-20
Transformation: rightward translation of 3 units and downward translation of 20 units.

Note: I can't insert the graphs here (maybe I can send you the graphs if you want).

(b)
(i)
x^3+10 = 0
You can read the result from the graph of y = x^3+10. Find the value of x when y = 0.
Ans: -2.2

(ii)
(x-3)^3 -20
You can read the result from the graph of y = (x-3)^3-20. Find the value of x when y = 0.
Ans: 5.7
