1. Let f(x)=sin(e^x)(adsbygoogle = window.adsbygoogle || []).push({});

a. Find 2 values of x satisfying f(x)=0

b. What is the range of f(x)

c. Find the value(s) of x that maximize f on [3.8,4] (use calculus)

2. y=e^x if and only if x=ln y

3.a. x=-infinity because the limit of e^x as x approaches -infinity is 0. and also, x=infinity because limit e^x as a approaches infinity=infinity

b.The range of f(x) is (0,infinity)

c. the values of x that maximize f on 3.81 and 3.95
