Mathematics problems in senior high school entrance examination
Let x = 0 and y belong to R.

get

F (0) = 0 power of f (y) = 1.

Let x belong to r and y= 1

F (x) = the x power of f (1)

Know from the meaning of the question

f( 1)>0

(If

F( 1)=0, then f(x) is a constant =0, which is inconsistent with the given range).

F (1/4)) =1/the power of 4 f (1) < 1

So f (1/4) < 1

Namely 0

2 times f( 1) squared = Party A+Party B > 2ab.

(Because A is not equal to B, you can't bring an equal sign)

Square of F( 1) >: ab

Take the logarithm based on f (1) (because 0

2 & ltab logarithm with base F (1)= a logarithm with base F (1)+b logarithm with base F (1) =f inverse (a)+f inverse (b).

The inverse function of y=f(x) is the logarithm of y=log of x with f( 1) as the base.
