WebJan 9, 2024 · One way to solve the problem is to note that the factor (x – 3) is positive when x > 3 and the factor (x – 4) is positive when x > 4. You can use these two points to cut the number line into three intervals: x < 3; 3 < x < 4; and x > 4. Then look at the sign of the quadratic in each interval. WebA function f from X to Y. The set of points in the red oval X is the domain of f. Graph of the real-valued square root function, f ( x) = √x, whose domain consists of all nonnegative real …
