2. kelsey has a list of functions. pick one of the g(x) functions below and then describe to kelsey the key features of g(x), including the end behavior, y-intercept, and zeros. o g(x) = x3 − x2 − 4x + 4

Answer with explanation:

g(x)=x³-x²-4 x +4

     =x²×(x-1)-4×(x-1)

     = (x²-4)(x-1)

     =(x-2)(x+2)(x-1)

Use the identity ⇒a²-b²=(a-b)(a+b)

So,Zeroes of Cubic function can be obtained by putting g(x)=0

→(x-2)(x+2)(x-1)=0

 → x= 2, -2, 1  

All the three zeroes of Polynomial g(x) are Real.

Put,x=0 to obtain Y intercept.

⇒g(0)=0³-0²-4×0+4

→g(0)=4-----Y intercept

⇒g(x) increases first ,then Decreases and again it increases.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
