Answer:
D. The graph of function
is the graph of function
shifted 4 units to the left.
Step-by-step explanation:
the function
is composite function between
and
, then you can re-write
as:

The transformation happened in the input, then you have an horizontal shifted and how it's adding 4 units then you go "faster" and move to left the graph.
In the image you can see what's mean sum a constant in the
of a function.
Answer: 9,2
Step-by-step explanation:
a+c=11
a=11-c
22(11-c) + 15c = 228
242-22c + 15c = 228
-7c=-14
C = 2 (two children)
Remember how a + c = 11
a + 2 = 11
A= 9
9 adults, 2 children.
Answer: (-3,6)
