Stanley analyzes the table of values for a polynomial function. he has determined through applying descartes rule of sign there is 1 negative real zero, and either 1 or 3 positive real zeros. he has also determined that the upper bound of the function is 3.
what is the degree of the polynomial function? how can you tell? how many positive real zeros does the function have? how can you tell?

4 + 5 7/9= 9 7/9

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
