Which of the following functions is symmetric about the y-axis? A. f(x) = 25 – 2x3
3x
B. f(x) = 2x3
3x2 - 4x + 4
c. f(x) = 625 – 23
D. f(x) = 26 – 3x4 – 4x2

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .

step-by-step explanation:

one day the were 5 ducks, and their king told them to multiply their kingdom. so each went their own seperate way and met 4 other ducks on their journey.

when the ducks returned to their kingdom, it was discovered that there were 5 groups of 5 ducks. when the kind counted the number of ducks in total (including the ones he sent out earlier) he counted 25.

therefore 5 times 5 is 25.

the end. : )

this "question" looks more like a project is there any other info you can give me about this. it could be too complex for someone else to do on this website
