Example 2: Mention the degree of the function in the
following :
a) f( x ) = ?? - ???? first
b) f( x ) = ???? - (???? - ??) zero
c) f( x ) = ??(?? - ??????) third
d) f( x ) = ????(?? - ??)?? fourth
Example 3:
If f( x ) = ???? - ?? + ?? , then find f(-2) , f(0) , f( 3)
F ( -2 ) = 4 – (-2 ) + 3 = 9
F (0)=3
F( 3 ) = 9 – 3 + 3 = 9
Example 4:
If f( x ) = ???? - ???? , g( x ) = ?? - ??
a) find f(v??) + 3g(v?? ) = 2 - 3 v?? +3v?? -9 = -7
b) prove that f( 3 ) = g( 3 ) = 0
f( 3 ) = 9 – 9 = 0
g ( 3) = 3 -3 = 0 then
f (3 ) = g (3 )
