4 students still need to finish their science project because if you do
20 x 0.80=16
20-16=4
Answer:
the answer is 207
Step-by-step explanation:
using bodmas
Solution:- Let f and g be the functions such that
can be used to form a function which maps x in X to
in Z.
If z is a function of y, and y is a function of x, then z is a function of x. (transitive property)
Hence the composite function is given by
, defined by
for x in X.
Now , for the function g(x) into the function for f(x), we have to work from the inside out by substituting the expression. So by this way composition of function related to order of operations.
That's easy, here let me show you a example:
