Answer:

-30 - 4n

Step-by-step explanation:

-34, -38, -42, -46, -50 ...

the sequence first term is -34

a= -34

Common difference (d) = T2 - T1 = T3 - T2

d = -38- -34 = -42 -  - 38 = -38+34

d = -4

Formula for nth term

Tn = a + (n-1)d

Tn = -34 + (n -1)-4

Tn = -34 -4n + 4

Tn = -30 - 4n

= -30 - 4n

Which graph represents an odd function?<br><br>Answer by using: A, B, C, or D for each graph.
vladimir1956 [14]

Answer: The correct option is C.

Explanation:

A function is called an odd function if,

f(-x)=-f(x)

It means if the points are in the form of (x,y) then (-x,-y) is also in the graph.

Reason for correct option:

In option C, a point  (1,2),

It means,

f(1)=2

And we have another point (-1,-2).

f(-1)=-f(1)=-2

The other points are (2,3),(-2,-3),(3,-1),(-3,1),(4,0),(-4,0). Therefore the function is an odd function.

Reason for incorrect option:

In option A, a point is (1,3), therefore the value of function at x = -1 should be -3.

But the value of function is 1 at x=-1, therefore it is not an odd function.

In option B, a point is  (1,0), therefore the value of function at x = -1 should be 0.

But the value of function is -3 at x=-1, therefore it is not an odd function.

In option D, a point is (1,-1), therefore the value of function at x = -1 should be 1.

But the value of function is -1 at x=-1, therefore it is not an odd function.
