4) Evaluate the function when f(2).
f(x) = (x-2)(x+2)

Plug in 2 for x
f(2) = (2-2) (2+2)
= (0)(4) = 0
f(2) = 0

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
