Step-by-step explanation:
Part B: which company would charge less for cleaning 8 windows? Justify your answer.
Part C: How much money is saved by using the services of Company B instead of Company A to clean 6 windows?
an even function has symmetry about the x axis
this means that if you fold the graph over the y axis, the function will map over itself
in number terms, if f(x) is an even function, then f(x)=f(-x)
an example is f(x)=x²
an odd function has symmetry about the origin
it is kinda confusing, but if g(x) is an odd function, g(-x)=-g(x)
an example is g(x)=x³
the first one (f(x)) seems to be neither
h(x) one, notice for x=2 and -2, the values are negative of each other, this tells us that it's an odd function
g(x), replacing x with -x gives us -|-2x|+3=-|2x|+3, same function, even function
