Question

If f(x)= (e^x)-(x^2)/2, then find the value of f(4)-f(0).

Answer 1

substitute x = 4

f(4) = (e^4 - 4^2)/2

f(0) = (e^0 - 0^2)/2

get the values then find the difference

Answer 2

or you could leave it in exact form

Answer 3

I got that far, but i dont know what to do with the e^4

Answer 4

If \[f(x)=e^x- \frac{ x^2 }{ 2 } \] then find the value of \[f(4)-f(0)\]

Answer 5

You can leave e^4 as e^4 or if you are allowed you can approximate it by using your calculator

Answer 6

Oh. Okay thanks
