Question

For what values of the numbers a and b does the function below have maximum value f(1) = 4? (Round the answers to three decimal places.)
f(x) = axe^[b(x^2)]

no idea about this one...==

Answer 1

f(1)=4 ...1st eqn
f'(1) =0 ... 2nd eqn
solve for a and b

Answer 2

f ' (x)= ae^(bx^2)+ax*e^(bx^2)*2bx

is it right?

Answer 3

yep..

Answer 4

i mean,,seems right..
