Which of the following functions are polynomials? (Choose all that apply)
a) y = x+3
b) g(x) = x-3
c) f(x) = log2 (x-5)
d) h(x) = 27-1
e) p(x)= x - 2x - 4
f) (x) = 2x2 - 4x
g) m(x) = 2 x 102
h) b(x)=br-21

step-by-step explanation:

a .4y4

hope this !

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
