Step-by-step explanation:
The domain of a function are the values of that you can plug into the function
.
Values inside of a root must be non-negative, which means that must be greater than or equal to zero. We can set up an equation to find the domain:
With this, we know the domain of the function is .
The range of a function are the values that can have. Since the equation is a cube root, the value will always be non-negative, meaning the range of the function is
.
The missing value is 12 in a system of equations with infinitely many solutions conditions.
It is given that in the system of equations there are two equations given:
It is required to find the missing value in the second equation.
<h3>What is a linear equation?</h3>It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
We have equations:
Let's suppose the missing value is 'Z'
We know that the two pairs of equations have infinitely many solutions if and if they have the same coefficients of variables and the same constant on both sides.
From equation (1)
(multiply both the sides by 3)
...(3)
By comparing the equation (2) and (3), we get
M = 12
Thus, the missing value is 12 in a system of equations with infinitely many solutions conditions.
