我想問下呢兩條數計.
可唔可寫埋step牙唔該.
identify each transformation from the parent function f(x) = 開方x to g.
1) g(x) = 4 乘開方x
2) g(x) = -1/4 乘開方x
唔該哂:)

✔ 最佳答案
As the question mentioned, f(x) = root(x)1)
g(x) = 4 root(x)
g(x) / 4 = root(x)
g(x) / 4 = f(x)
Thus, f(x) = (1/4)g(x)
2)
g(x) = (-1/4) root(x)
(-4)g(x) = root(x)
(-4)g(x) = f(x)
Thus, f(x) = -4g(x)
