The graph of the function f(x) = -(x+3) (x-1) is shown below. what is true about the domain and range of the function

domain is  ( -∞ ,∞), Range  is ( -∞ ,1 ].

Step-by-step explanation:

Given : The graph of the function f(x) = -(x+3) (x-1).

To find  : domain and range of the function.

Solution : We have given that f(x) = - (x+3) (x-1).

Domain : The domain is the set of input values of x for which function is real and defined.

Since, domain is  ( -∞ ,∞).

Range : The range is set of dependent values for which function is defined.

Range  : ( -∞ ,1 ].

Therefore, domain is  ( -∞ ,∞), Range  is ( -∞ ,1 ].

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
