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:

f(x) -x ^ 3 -x

If we make f (-x) we are left with:

f(-x) = - (-x ^ 3) - (-x)\\\\f(-x) = x ^ 3 + x = -f(x)

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)

Option 1 and 2 and 3

Yes or course. PEMDAS
Parenthesis
Exponents
Multiplication-Division (solve left to right)
Addition- Subtraction (solve left to right)
example, lets take a simple equation.
32+6x7-1+4²
Let's solve it left to right 
You're answer would be 281
But when using PEMDAS your answer is- 89
