Find the definition of the scope of the function. y = √ (4-3x)

Let us find the definition of the domain of the function y = √ (4 – 3 * x). The domain of the function is the expression at the root greater than or equal to 0. That is, we get: 4 – 3 * x> = 0; We transfer the known values to one side, and the unknown ones to the other side. When transferring values, their signs change to the opposite sign. That is, we get: – 3 * x> = 0 – 4; – 3 * x> = – 4; When dividing an inequality by a negative number, the sign of the inequality changes to the opposite sign. That is, we get: x <= – 4 / (- 3); x <= 4/3; Answer: x <= 4/3.
