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.
Answer:
The lemonade costs 1.4.
Step-by-step explanation:
This question is solved using a system of equations.
I am going to say that:
x is the cost of a cookie.
y is the cost of a lemonade.
Total cost for cookie and lemonade is 1.80.
This means that .
As we want y, we have that
Lemonade costs 1.00 more than the cookie?
