f ( x ) ⋅ g ( x ) ⋅ h ( x ) = x − 1 ⋅ ( x 2 + 2 ) ( x + 3 ) = = ( x 3 + 3 x 2 + 3 x 3 + 9 ) x − 1 = ( 4 x 3 + 3 x 2 + 9 ) x − 1
The product of the functions f ( x ) , g ( x ) , and h ( x ) is expressed as f × g × h = x − 1 ⋅ ( x 3 + 3 x 2 + 2 x + 6 ) . This gives a single function by multiplying the linear, quadratic, and square root functions together. Ensure that x is greater than or equal to 1 for the square root to be defined.
