- (A) Although there is no elementary function (one made up of polynomial, trigonometric, or
exponential functions or their inverses) that is an anti-derivative of F ā²(x) = eāx^2 , we know from
the FTC, since F(0) = 0, that
To approximate use your graphing calculator
For upper limits of integration x = 50 and x = 60, answers are identical to 10 decimal places.
Rounding to three decimal places yields 0.886.
