Tentukan invers dari fungsi berikut

Invers

f(x) = √2x + 10
y = √2x + 10
y² = 2x + 10
2x = 10 – y²
x = (10 – y²) / 2
f-¹(x) = (10 – x²) / 2

g(x) = (4 – x) / (2x + 3)
y = (4 – x) / (2x + 3)
y(2x + 3) = (4 – x)
2xy + 3y = 4 – x
2xy + x = 4 – 3y
x (2y + 1) = 4 – 3y
x = (4 – 3y) / (2y + 1)
g-¹(x) = (4 – 3x) / (2x + 1)
x ≠ -½
