I am sure we need more information to determine an answer to question 1.
for the second question, read this
1.Suppose g is a given function and let h= f o g . IS h always an even funciton ?
a) Write an equation that defines the exponential function with basea > 0
(b) What is the domain of this function?
(c) If a ≠ 1, what is the range of this function?
(d) Sketch the general shape of the graph of the exponential function for each of the following cases
(i) a >1 (ii) a =1 (iii) 0 < a <1
