Verify Property 2 of the definition of a probability density function over the given interval. f(x) = 78X. [0.6] What is Property 2 of the definition of a probability density function? O) A. The area under the graph of f over the interval [a, b] is 1. O B. The area under the graph of f over the interval [a,b] is b. O C. The area under the graph of f over the interval [a, b] is a. Identify the formula for calculating the area under the graph of the function y = f(x) over the interval [a,b] Choose the correct answer below. OA. a OB. b (( x ) dx = [F(x)].=F(a)-F(b) "(x) dx = [F(x)]> =F(a) -F(b) O C. OD. b "(x) dx = [F(x)]; =F(b)-F(a) (x) edx = [F(xx)], =F(b) -F(a)
