The answer should be last one: (-∞,0)
Because that's what the pic shows you.
A function being even or odd refers to the symmetry of the graph.
Refer to the graphs attached to this answer.
To test if a function is even or odd, replace x in the function with -x. If the new graph is exactly the same as the old graph, the function is even. If not, multiply the entire function by -1. If the new graph is symmetrical to the y-axis, then the function is odd. If it isn't symmetrical, the function is neither even nor odd.
The first graph is the original function. The second graph is the function with x replaced by -x. The third graph is the function multiplied by -1.
The second graph is not equal to the original function. The third graph is symmetrical to the y-axis.
This function is
odd.
Answer:
B) 112°
Step-by-step explanation:
After the double reflection the point is effectively rotated by an amount that is double the angle between the lines of reflection:
2·56° = 112°
_____
In the attached, lines l and m are separated by 56°, as required by the problem statement.
Answer:

Step-by-step explanation:
The given equation is

According to the rational roots theorem, the possible rational roots are all factors of the constant term, expressed over all
factors of the leading coefficient.
The factors of the leading term, 1 are:
±1
The factors of the leading coefficient are:
±1
The possible rational roots are:

93
Straight lines are equal to 180, therefore 180-56 gives you 124 for the opposite angle to x. Adding 56, 124 and 87 gives you 267. 360-267=93
