You can put this solution on YOUR website!
find (a)f o g (b)g o f .find the domain of each function and each composite funcition.
\n" ); document.write( "Given: f(x)= x^2 +1 g(x)=square
\n" ); document.write( " root of x\r
\n" ); document.write( "\n" ); document.write( "i can find f(g) and g(f) but i cant find the domains
\n" ); document.write( "OK....DOMAIN I SHALL TELL YOU..
\n" ); document.write( "THE VALUES X CAN TAKE TO MAKE THE FUNCTION REAL IS DOMAIN.
\n" ); document.write( "IN THE FIRST CASE
\n" ); document.write( "F(X)=X^2+1....X CAN TAKE ANY REAL VALUE..SO DOMAIN IS ALL REAL NUMBERS.
\n" ); document.write( "IN SET NOTATION WE WRITE IT AS (-INFINITY,+INFINITY)
\n" ); document.write( "IN THE SECOND CASE
\n" ); document.write( "G(X)=SQRT(X)
\n" ); document.write( "NOW IF X IS NEGATIVE THE FUNCTION BECOMES IMAGINARY..HENCE X CANNOT BE NEGATIVE.
\n" ); document.write( "SO WE SAY DOMAIN OF X IS ALLREAL VALUES GREATER THAN OR EQUAL TO ZERO.
\n" ); document.write( "IN SET NOTATION WE WRITE IT AS (0,INFINITY)
\n" ); document.write( "
\n" );
