Content intersection and complement set, and power exponential pair function. Parity and increase and decrease are the most obvious observation images.

When the compound function appears, the law of property multiplication is distinguished. To prove it in detail, we must grasp the definition.

Exponential function and logarithmic function are reciprocal functions. Cardinality is not a positive number of 1, and 1 increases or decreases on both sides.

The domain of the function is easy to find. Denominator cannot be equal to 0, even roots must be non-negative, and zero and negative numbers have no logarithm.

The tangent function angle is not straight, and the cotangent function angle is uneven; The real number sets of other functions have intersection in many cases.

Two mutually inverse function have that same monotone property; The images are symmetrical with y = x as the symmetry axis.

Solve the very regular inverse solution of substitution domain; The domain of inverse function, the domain of original function.
