Is the below function correct? does it execute properly for all inputs? declare powa local powacc in powacc = fun {$ x n acc} if n==0 then acc else {powacc x n-1 x*acc} end end powa = fun {$ x n} {powacc x n 1} end end

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo
