Answer:
x = 4 - 6y.
Step-by-step explanation:
4x + 2y = 3
6y = 4 - x
-x = 6y - 4
x = 4 - 6y is the required expression.
For every polynomial function (such as quadratic functions for example), the domain is all real numbers. if the parabola is opening upwards, i.e. a > 0 , the range is y ≥ k ; if the parabola is opening downwards, i.e. a < 0 , the range is y ≤ k .
