You copied it down wrong.

f(x) = e^x - x^2

f'(x) = e^x - 2x

(You got that part right)

But when you substituted you treated -2x as - x^2

It should be:

f'(1.234) = e^(1.234) - 2(1.234) = 3.435 - 2.468 = 0.967

#2

F'(x) = e^3x

Therefore,

F(x) = 1/3 * e^3x

(You multiplied it by 3 instead of divide it by 3)

therefore,

F(1.234) = 1/3 * e^(3.702) = 1/3*40.528 = 13.509

Thats pretty much it.

I bow down to the DigiMon master if that is correct...
