Find constants c and d such that f(x)=x4 +cx + d is divisible by (x+2)2.
(That means when f(x) is divided by (x+2)2, remainder is 0)

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
