Helppp please!!!!!!!!

8 = 4 - 2x<br> - 2x +5 = 17<br> 12= - 3 ( x+ 5)

max2010maxim [7]

$8 = 4 - 2x\\8 + 2x = 4\\2x = -4\\x = -2$

$- 2x +5 = 17\\-2x =12\\x = -6$

$12= - 3 ( x+ 5)\\12 = -3x -15\\-3x =27\\x= -9$

Which of the following is an odd function

nika2105 [10]

Given the functions

(a) f(x) = x³ + 5x² + x

(b) f(x) = x² + x

(c) f(x) = -x

Function (a)

f(-x) = (-x)³ + 5(-x)² + (-x)

= -x³ + 5x² - x

= -(x³ - 5x² + x)

The function is neither even nor odd.

Function (b)

f(-x) = (-x)² + (-x)

= -(-x² + x)

The function is neither even nor odd.

Function (c)

f(-x) = -(-x)

= x

= -f(x)

Because f(-x) = -f(x) the function is odd.

Answer: f(x) = -x is an odd function.
