1. Let f(x) = x2 + 4x and g(x) = |1 - x|. Determine (f o g)(7.1).
2. By utilizing the calculator, approximate e^-1.8 to 4 decimal places.
3. Decide whether or not functions are inverses of each other:f(x) = 6x + 3; g(x) = x/6 - 3
4. Find out whether given function is exponential or not. If it is exponential, identify value of base a.

a. exponential; a = 13
b. exponential; a = 5
c. exponential; a = 8
d. not exponential
5. Compute inverse of f(x) = (x + 2)3 - 8 if possible.
6. By utilizing the calculator, approximate value of 2.4^2.6 to 4 decimal places.
