B, f(x) where the number in the parenthesis is what u substitute for x in ur expresstion

anonymous · Answer

what you are doing in f(12)is plugging 12 in for x

when 7x - 1 = 12
7x = 12 + 1
x = 13 / 7


the value of ( 7x - 1 ) when x = 12
7 ( 12 ) - 1 
84 -1
83

because f(12) = translating 12 to x
