Describe the end behavior of each polynomial functions. Write RR if it rising to the left and right, FF if its falling to both left and right, FR if it rising to the left and rising to the right and RF if it rising to the left and falling to the right

1.) f(x) = 2x³ + x² + 3x - 4

Highest power of variable is 2x³

Degree of the f(x) = 3, ODD

Leading coefficient  = 2, positive

FR

2.) f(x) = -5x⁴ + x³ - 3x² - 8x + 15

Highest power of variable is -5x⁴

Degree of the f(x) = 4, EVEN

Leading coefficient  = -5, negative

FF

3.) f(x) = 3x⁴ - 8x³ - 2x² + 9 - x

f(x) = 3x⁴ - 8x³ - 2x² - x + 9

Highest power of variable is 3x⁴

Degree of the f(x) = 4, EVEN

Leading coefficient  = 3, positive

RR

4.) f(x) = -x³ - 3x² - 2x + 1

Highest power of variable is -x³

Degree of the f(x) = 3, ODD

Leading coefficient  = -1, negative

RF

5.) f(x) = x² - x⁴ + 8

f(x) = -x⁴ + x² + 8

Highest power of variable is -x⁴

Degree of the f(x) = 4, EVEN

Leading coefficient  = -1, negative

FF
