Answer:
Step-by-step explanation:
Assuming you are saying f(x) =[ (3/4) x] +2 and ask for f(12)
f(12) = [(3/4) (12) ]+2, substitute x with 12
f(12) = [(3·12)/4 ] +2, multiply a number and a fraction
f(12) = (3·3·4/4) +2, rewrote 12 as 3·4 so we can simplify
f(12) = (3·3) +2, we will consider the order of operations and do the multiplication first
f(12) = 9+2 , add
f(12) = 11
