the second one
Step-by-step explanation:
E(x) = (499*0 + 1000) / 500 = 2$
5$ + 2$ = 7$
7$ / 5$ = 1,4 => payback ratio = 40%
Bobby is right, because at x = -2, 3, and 5, the denominator of the function equals zero, which is by definition undefined.
It’s -7
Because you subtract -2 with 7 and it equals 5x=-35 and then u divide it and it equals -7
