Which statement is NOT true about the normal probability density function? A. It is also known as the bell curve.

B. Its shape is completely concave downward.

C. It has 2 inflection points.

D. It has reflectional symmetry.

The correct answer is

B. Its shape is completely concave downward.

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
