Answer:

r = 4, s = 3, t = 5

Step-by-step explanation:

Solving quadratic equation:

5x² - 8x + 5 = 0
x = (-b ± √b²-4ac)/2a
x = (8 ± √8²-4*5*5)/2*5
x = (8 ± √64-100)/10
x = (8 ±√-36)/10
x = (8 ± 6i)/10
x = (4 ± 3i)/5

x = (r ± si)/t

r = 4, s = 3, t = 5

Which of the following is an odd function

nika2105 [10]

Given the functions

(a) f(x) = x³ + 5x² + x

(b) f(x) = x² + 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.
