The correct answer is - Temperate highland.
The climate type in Brazil, in which the snow is a common occurrence in certain period of the year, is the temperate highland climate zone. It is located in the southern part of the country, and it is a climate zone where the dominant land features are the highlands.
Snow can occasionally occur in the other climate zones, like the temperate oceanic (also in the southern part of the country), or even in the tropical monsoon climate zone in the southeastern part of the country, but that is very rare.
Answer: D [-1,1]
is the inverse of function g(x).
the inverse equation of g(x) = sin(x):
sin(y) = x
y = 
(x)
using a trig circle with radius 1, we can find out that the max values of sin(x) are 1 and -1, so the domain of the inverse of sin(x) must be [-1,1]
**Note: if allowed during AP test, test from school. or assignment, you can use your graphing calculator to graph (x)
