choose the letter of the correct answer.

1. why are exponential and logarithmic functions called inverses?

a. from an exponential function, you can get a logarithmic function by interchanging x and y, then solving for y.

b. from a logarithmic function, you can get an exponential function by interchanging x and y, then solving for y.

c. the graphs of an exponential function and the corresponding logarithmic function are symmetric with respect to the line y=x

d. a and b

e. a and c

f. all of the above

answer the questions briefly. clear and concise

2. why can't the base of exponential and logarithmic functions be equal to 1?

3. why can't the base of exponential and logarithmic functions be nonnegative?
