Question

When x is an odd number, the function f(x) = 2(x + 2) gives an even number. Identify the set of even numbers that correspond to this set of odd numbers that satisfy the function.
{41, 57, 77, 83, 95}

Answer 1

F(x) = 2(x + 2)

f(41) = 2(41 + 2)...2(43) = 86
f(57) = 2(57 + 2)...2(59) = 118
f(77) = 2(77 + 2)....2(79) = 158
f(83) = 2(83 + 2)...2(85) = 170
f(95) = 2(95 + 2)...2(97) = 194
