How to find the standard deviation and variance of 93,73,76,86,98?

Mean = (93 + 73 + 76 + 86 + 98) / 5 = 426/5 = 85.2

Variance = ((93 - 85.2)^2 + (73 - 85.2)^2 + (76 - 85.2)^2 + (86 - 85.2)^2 + (98 - 85.2)^2) / 5 = (60.84 + 148.84 + 84.64 + 0.64 + 163.84) / 5 = 458.8 / 5 = 91.76

standard deviation = sqrt(91.76) = 9.58

Both graphs have exactly one asymptote & both graphs have been shifted and flipped ( apex)
