Answer:
f⁻¹(x) = eˣ / 3
Step-by-step explanation:
f(x) = In(3x)
y = In(3x)
swap x and y: x = In(3y)
solve y: eˣ = 3y
y = eˣ / 3
L=2w-6
area = L x W
108=(2w-6)w
108 = 2w^2-6w
2w^2-6w-108 = 0
2(w^2-3w-54)=0
2(w-9)(w+6) = 0
w=9
L= 2(9)-6 = 12
12*9 = 108
SW =XW and ST=XU and UW=TW
All are true and correct since the two triangles are congruent
