Which functions are more likely to appear in the college entrance examination?
Function images are more likely to appear in college entrance examination mathematics examination. The following are some common function image types:

1. quadratic function: such as y = ax 2+bx+c (a ≠ 0), Y = A (X-H) 2+K (A ≠ 0), etc. This kind of function images often appear in college entrance examination questions, especially those related to vertices, symmetry axes and maxima.

2. Exponential function: y = a x(a >;; 0, a≠ 1) and y = a (-x) (a >; 0,a≠ 1)。 This kind of function image is also very common in college entrance examination questions, especially when solving problems related to logarithmic operation and exponential operation.

3. trigonometric functions: images of sine function sin(x), cosine function cos(x) and tangent function tan(x). This kind of function image usually appears in solving triangle related problems or physical problems in college entrance examination questions.

4. Power function: y = x a (a ≠ 0). This kind of function image rarely appears in college entrance examination questions, but it may be encountered in some questions involving exponential operation or power series.

5. piecewise function: the form is y=f(x)={u(x), xgeq0v(x), x.

6. Compound function: a function consisting of two or more basic elementary functions, such as y=f(g(x)). This kind of function image rarely appears in college entrance examination questions, but it may be encountered in some complicated mathematical models or practical problems.

In a word, function images are more likely to appear in the college entrance examination, but the specific questions and difficulties may be different due to different examination papers and regions. Therefore, it is suggested that candidates review various function images and their properties in order to better cope with the college entrance examination questions.
