1. what is the doamin and range form this graph and the minimum and maximum and interval of increase and decrease?​

Below.

Step-by-step explanation:

The Domain is all real values of x.

The range is  -6 ≤ f(x) < ∞.

( I cant see the minimum value very clearly but I think its -6).

Minimum -6 Maxm ∞.

Decreasing from f(x) = -∞ to f(x) = -6.

Increasing from f(x) = -6 to ∞.

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1

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
