We use this operator mainly when we wish to emphasize the relationship between the functions themselves without referring to any particular input value. For instance if $f(z)=1/z$ and $h(x)=2+3x$ then and the radius is a function of the circumference (r = C/(2\pi)). Because the inequality is ?greater than or equal to?. In division, the number being divided is the dividend, the number that divides it is the divisor, and the result of the division is the quotient. background:#133c6d; composition operator The open circle symbol is called the composition operator. } The square bracket on the left indicates that the number line begins with 5 and that 5 is included in the solution set. Example 1: Evaluate the ceiling function of 4.5 and - 4.5. This is written as "( f o g)(x)", which is pronounced as "f-compose-g of x". On a number line graph, a solid dot indicates that the given number should be included as a potential solution, whereas an open dot implies that the given number cannot be a solution. /*
