The lower limit of the integral in each case is $0$, and the upper limit is $a$. This will give a positive sign in the answer.

Also, each result can be simplified, by dividing by $a$.

Hello grandad
Thank you for welcome
I think I have the correct answer now,from your kind help
g(x) functions answer would be a^2/(3), and the first part f(x) works out a/(2)
is this correct please?(Clapping)
