چکیده
cannot be a probability density function. To see this, note 2x− x = −x(x− √ 2)(x+ √ 2). If C = 0, then f(x) = 0 for all x, so ∫∞ −∞ f(x) = 0, but every probability density function has ∫∞ −∞ f(x) = 1. If C > 0, then f(x) < 0 on the range x ∈ (0, √ 2), but every probability density function has f(x) ≥ 0 for all x. If C < 0, then f(x) < 0 on the range x ∈ ( √ 2, 5/2), but every probability density function has f(x) ≥ 0 for all x. So no value of C will satisfy all of the properties needed for a probability density function. 3b. The function
