Which of the following shows all of the possible rational roots for the function f(x)=2x^4-5x^3+9x^2+7? * 5 points
±1, ±7
±1, ±7, ±14
±1, ±7, ±1/2, ±7/2
±1, ±7, ±1/2, ±7/2, ±14

c

Step-by-step explanation:

q: 2

p:7

factors of 2 are 1 and 7

factors of 7 are 1 and 7

multiple combinations of them each. p/q

1/1, 7/1, 1/2, 7/2

simplyfies to 1, 7, 1/2, and 7/2

what is the answer?

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
