Diberikan k(t) = (t + 2)^5 - 4 .Rumus k^-1(t) = ...

jawab

k(t) = (t+2)⁵ - 4
(t+2)⁵ = y + 4
t+2 = ⁵'√ (y+4)
t = ⁵'√(y+4)  - 2

k⁻¹ (t) = ⁵'√(t+4) - 2

Fungsi Invers

k(t) = y
y = (t + 2)^5 - 4
(t + 2)^5 = y + 4
t + 2 = (y + 4)^(1/5)
t = (y + 4)^(1/5) - 2

Invers dr k(t) :
k^-1 (t) = (t + 4)^(1/5) - 2
