Which of the following functions are odd?
2 answers:
Answer:
Option 1, 2 and 3
Step-by-step explanation:
A function f(x) is odd if f(-x) = -f(x).
The graphs of odd functions are symmetric with the origin.
It is also known that the sum of two odd functions results in an odd function, so <em>the third option is an odd function.</em>
The first option shown is:
If we make f (-x) we are left with:
The function is odd.
The second option is a graph that has rotational symmetry of 180 ° with respect to the origin, that's why it is odd function.
The rest of the options are not odd functions because it is not true that f(-x) = -f(x)
