If the equation is then the domain is the set of all real numbers.
We can replace x with any real number and compute to get some real number output for y. There are no division by zero restrictions to worry about, or issues with taking a square root of a negative number (since this isn't really a square root function).
The cube root of a negative number is negative. For example, because (-4)^3 = (-4)*(-4)*(-4) = -64.
In interval notation, the domain would be written as to indicate the entire real number line.
(-1,4)(2,3)
slope = (3-4) / (2-(-1) = -1/3....a parallel line will have the same slope
y = mx + b
slope(m) = -1/3
(4,-2)...x = 4 and y = -2
now we sub
-2 = -1/3(4) + b
-2 = - 4/3 + b
-2 + 4/3 = b
-6/3 + 4/3 = b
-2/3 = b
equation in slope int form is : y = -1/3x - 2/3
y = -1/3x - 2/3
1/3x + y = - 2/3...multiply by 3
x + 3y = - 2
x + 3y + 2 = 0 <== general form
