Answer:
-f(-x) = f(x)
Step-by-step explanation:
Given function is:
f(x)= -2x^5+x^3-7x
To check if a function is even, it is checked that:
f(-x)=f(x)
If f(-x) gives the original function then the function is said to be even.
And if:
-f(-x)=f(x)
which means if –f(-x) gives the original function, then the function is odd. So a function has to satisfy this rule to be an odd function.
Now for the given function:
-f(-x)= -[-2(-x)^5+(-x)^3-7(-x)]
= -[(-2)(-x^5 )+(-x^3 )+7x]
= -( 2x^5- x^3+7x)
Multiplying the negative sign
-f(-x)= -2x^5+x^3-7x
-f(-x)=f(x)
So, the function satisfies this rule to be an odd function. ..
Answer:
257/2
Step-by-step explanation:
So in condition we need to know π=180 so when you multiply by π/180 or 180/π is one
it says we need to change from radian to degree so we need time 180/π
so it like this:
(257π)/360*(180/π)=257/2.
The terms are written in descending order of degree
Here the answer is D

The answer is the first one.
