Answer:
The correct options are:
- g(x) is shifted three units higher than f(x).
- g(x) has a period that is half the period of f(x).
Step-by-step explanation:
We have to compare the graphs of the function:
and
We have to select the correct options among the following:
As we know that the period of sine function is 2π.
i.e. Period of function f(x) is: 2π.
The period of sin(2 x) is π.
Hence, the period of the function g(x) function is π.
- Hence, the period of g(x) is half the period of f(x).
- Also we could observe that g(x) is shifted 3 units upward.
Answer: There are 140 adults and 40 children.
Step-by-step explanation:
Let 2x = Number of children
7x = Number of adults.
As there are 100 more adults than children.
That means,
Number of children = 2 (20)=40
Number of adults = 7(20) = 140
Hence, there are 140 adults and 40 children.
