Answer:
C
Explanation:
H(4) simply means that where there is X, it must be substituted by the value 4
So lets see step by step:
A. h(4)=2 (incorrect)(there is no X to substitute on the right side and it is stated that H is non linear. This 2 would mean that H is a straight line)
B. (4)^3 -4= 60 (incorrect as answer needs to be 2)
C. 2^4 - 14=2 (correct, as answer is 2 and equation is non linear)
D. 1/2 (4) +3 = 5 (incorrect)
Hence your answer is C
