Answer:
x = 50°
Step-by-step explanation:
the sum of the exterior angles of any polygon is 360°
2x-12 + 32 + 2x + x + 90 = 360
5x + 110 = 360
5x = 250
x = 50

Answer:
The equation  is a function, for each value of x, corresponds a y-value. The domain and the range is for all the real numbers.
 is a function, for each value of x, corresponds a y-value. The domain and the range is for all the real numbers.
Step-by-step explanation:
To sketch the graph you need to make a table, propose different values of x, including negative and positives. You can see that for any value of x, you will have any value of y.
For example:
x	y
-20	-59
-15	-44
-10	-29
-5	-14
0	1
5	16
10	31
15	46
20	61
Remember the following concepts:
The domain of a function f (x) is the set of all the values for which the function is defined. In other words is the collection of all possible inputs that can be plugged into a function to produce a y-value. To find the domain depends of the function type. For example a polynomial function without radicals or variables in the denominator will have all the real numbers in its domain. Usually we have to avoid 0 on the bottom of a fraction, or negative values under the square root sign.
The range of the function is the set of all the values that y takes, it is the collection of all possible outputs, depending of the function can have a minimum y-value or a maximum y-value.
We can see that the function y = 3x +1, or f(x) = 3x +1, has no restrictions, therefore the domain is all real numbers. From the graph we can see easily that y can be positive or negative. So the domain and the range can be expressed as (-∞, ∞)
