Let fx x 3 and gx x2 x Find and simplify the expression
Let f(x) = x - 3 and g(x) = x^2 - x. Find and simplify the expression (f middot g)(a). (f middot g)(a) = (Use integer or fractions for any numbers in the expression.)
Solution
Given that f( x ) = x - 3 and g( x ) = x2 - x
Then consider ( f . g ) ( x ) = f ( g ( x ) ) = f ( x2 - x ) = x2 - x - 3
Therefore , ( f . g ) ( x ) = x2 - x - 3
