حل السؤال 15، 4MA1/2H يناير 2020: التعرف على أشكال التمثيلات البيانية ورسمها

1. 1y = 2^(2x) is an exponential curve: it stays above the x-axis and climbs steeply as x increases, so it is Graph C.
2. 2y = −(1/2)x³ is a cubic with a negative coefficient: it comes down from the top left, passes through the origin, and continues to the bottom right, so it is Graph B.
3. 3y = −5/x is a reciprocal curve: two separate branches, one in the second quadrant and one in the fourth, with the axes as asymptotes, so it is Graph E.
4. 4The letters are C, B, E.

AnswerC, B, E
