Answer:
Yeah i don't get it i have the same problem
Answer:

Step-by-step explanation:
(w circle r) (x) is the composite function(w of r(x)), that is, w(r(x))[/tex]
We have that:


Composite function:

is a negative parabola with vertex at the original.
So the range(the values that y assumes), is:

Answer:
f(x) = 4^x
Step-by-step explanation:
In f(x) = (1/4)^x, 1/4 is equal to 0.25, which is less than 1, so its decreasing
In f(x) = 4^x, 4 is greater than 1, so its increasing
In f(x) = (0.4)^x, 0.4 is less than 1, so its decreasing
This is why f(x) = 4^x is the correct answer
I hope this helps!

Step-by-step explanation:
First exercise:
We have a right triangle with the values of each side an we have to find the following trigonometic functions (taking into account the secant function
is the inverse of the cosine, the cosecant
is the inverse of the sine):
1) 

2) 

Then:

3) 

Then:

4) 
Then:

Second exercise:
5) Here, we are given another right triangle and we have to find the measure of the angle
.
So, according to the figure, we can use the tangent function:
