WebFind the domain: f (x) = x 2 − 4. Solution: Recall that the argument of a square root function must be nonnegative. Therefore, the domain consists of all real numbers for x such that x 2 − 4 is greater than or equal to zero. x 2 − 4 ≥ 0. It should be clear that x 2 − 4 = 0 has two solutions x = ± 2; these are the critical values. WebThe second inequality is y is less than 2x minus 5. So if we were to graph 2x minus 5, and something already might jump out at you that these two are parallel to each other. They have the same slope. So 2x minus 5, the y-intercept is negative 5. x is 0, y is negative 1, negative 2, negative 3, negative 4, negative 5.
