Which is a possible turning point for the continuous function f(x)? (–2, 0) (0, –2) (2, –1) (4, 0)

Turning points:

All points on the function where function changes it's shape

At turning point , it will either go from increasing to decreasing or from decreasing to increasing

We can see hat

as x increase upto x=0

The value of y decreases

x-value: -6 , -4 , -2 , 0

y-value: 8 , 2, 0 , -2

But f(x) changes from -2 to -1 ..

so, it is increasing

so, function changes at x=0

that's why turning point is

(0,-2)Answer

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

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
