Let
f(x) = 2x-3 for x < -1,
(2/3)x-1 for x =
-1, (3/7)x-2 for
x >
-1,
and let
g(x)=(-6/7)x for x >= 3, 0.5x-1 for x < 3.
Write, run, and test a Fortran 90 program which computes (fog)(x),
where (fog)(x)=f(g(x)).
Input: x, where x is any real number.
Output: (fog)(x).
Here is a sample run (your program should do exactly the same thing):
======== Sample run starts
here. ========
Enter your value of x:
-2.0
(fog)(-2.0)=-7.0.
======== Sample run ends
here. ========
You should only use the material which we covered by
Sep., 8.
DO NOT forget to run and test your program. Also,
make sure that it
has no logical errors (i.e. it gives you right answers.)
