Transcribed Image Text:2. In this problem we make our own exponential function.
Create a Matlab function whose prototype is: y = myExp (x) where the input x is a floating point number and
the output y is the floating point approximation to y = e. In writing this function you are only allowed to
use the operations of arithmetic (+ x +), absolute value (1) and any programming control statements
you need. Your function should be accurate to 8 significant digits.
(a) How have you computed e*?
(b) How have you insured the desired accuracy?
(c) How did you test your function?
(d) In theory, what is the largest value of x your function will take without an overflow error? Explain.
