The functions are:

i) g(x)=3\cdot \sin(x+ \pi )

ii) f(x)=2 \cos(x).


We note that both Sin and Cos functions cannot produces values smaller than -1, or larger than 1.

In other words, the range of both these functions is [-1, 1]. 

Whatever expression A is, sin(A) and cos(A) are values in [-1, 1].


Assume \sin(x+ \pi ) produced its maximal value, 1, then 3\sin(x+ \pi ) makes this value 3.

Thus, the maximum value of g(x) is 3, as can be also seen in the graph.

Similarly, assume cos(x) produced 1, then 2cos(x) makes it 2. Thus, the greatest value of f(x) is 2.


Answer: max{f(x)}=2, max{g(x)}=3, so g has the largest maximal value.

Please help a girl out :)
Vilka [71]

Answer:

1/6

Step-by-step explanation:

I don't know how to use it using a number line sorry

-1/3 - (-1/2)

Two minuses give us a plus

so:

-1/3 + 1/2

make the denominators the same and what you multiply at the bottom you multiply at the top (check online about adding fractions if you don't understand)

so:

-2/6 + 3/6 = 1/6
