use the given function to answer a through f
f(x)=ln(2x)+5
a. domain: (0,∞)
b. graph f (see graph below)
..
c. determine range and vertical asymptote
vertical asymptote: y-axis or x=0
range: (-∞,∞)
..
d. find f^-1
interchange x and y and solve for y which is the inverse
x=ln(2y)+5
x-5=ln(2y)
convert to exponential form
e^(x-5)=2y
y=e^(x-5)/2=f^-1
..
e. find domain and range for f^-1
domain: (-∞,∞)
range (0,∞)
Horizontal asymptote: x-axis or y=0
f. graph f^-1 (see graph below)
