on a pure function for a list of integrals

Thanks, Jean-Marc, you suggest

f = Block[{x, a = #1, b = #2},
         (NIntegrate[Sqrt[a*x + b], {x, 0, #1}] & ) /@ #3] & ;
f[2, 3, {0.1, 0.5, 0.9}]

but I think there are assignments which are never used as

In[1]:= f = Block[{x},
         (NIntegrate[Sqrt[a*x + b], {x, 0, #1}] & ) /@ #3] & ;
f[2, 3, {0.1, 0.5, 0.9}]

gives me exactly the same result so the bit a = #1, b = #2 seems unnecessary
