HELP PLEASE Which of the following graphs could be the graph of the function f(x)= -0.08x(x^2-11x+18)?

see below

Step-by-step explanation:

f(x)= -0.08x(x^2-11x+18)

Factor

f(x)= -0.08x(x-9)(x-2)

Using the zero product property to find the zeros

0= -0.08x(x-2)(x-9)

-0.8x =0    x-2 =0  x-9 =0

x=0            x=2           x=9

Multiply out

f(x) =  -0.08 x^3 + 0.88 x^2 - 1.44 x

The highest power is x^3

f(-∞) = -0.08( -∞)^3 = - ( -∞) = ∞

As x goes to -∞  f(x) goes to +∞

f(∞) = -0.08( ∞)^3 = - ( ∞) = -∞

As x goes to ∞  f(x) goes to -∞

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

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
