Answer:
C. symmetric with respect to the origin
Step-by-step explanation:
A graph must pass the vertical line test to be called the graph of a function. No function will ever be symmetrical with respect to the x-axis, because that would mean it fails the vertical line test.
An even function is symmetrical about the y-axis. An even function has the characteristic that ...
f(-x) = f(x) . . . . an even function
An odd function is symmetrical about the origin. An odd function has the characteristic that ...
f(-x) = -f(x)
__
The given function is f(x) = -1/x. Then the value of f(-x) is ...
f(-x) = -1/-x = 1/x = -f(x)
The given function is an odd function, so is symmetrical about the origin.
It is 9 because you need to triple 3 so 3x3 is 9
The nearest 10 dollars would be $70.
And 25% of 70 is 17.50
So 17.50 should be correct.
Answer:
All are rational numbers.
Step-by-step explanation:
A rational number can be written in the form:

where a and b are integers and b≠0.
We can rewrite 136 as

hence 136 is a rational number.
715-245=470....is an integer and hence a rational number.
(47)(217)=10199....which is an integer, and all integers are rational numbers.

15 is also an integer and hence an integer.
