Question 5: How do you prove that a Function is Onto? The general form of cubic function is f(x) = ax 3 + bx 2 + cx +d, and if f(a) = 0, then x-a is the factor of this cubic function. Question 4: How to Solve Cubic Functions? Question 3: Write the ways in which a function is represented.Ī function is represented as y = f(x) where, x is the input value and f(x) is the output value. Question 2: Define a function.Ī function is defined as a relation between a set of values where for each input we have only one output. A codomain of a function is defined as the set of all possible output values f that function. FAQs on Function Question 1: What is domain and codomain of a function?Ī domain of a function is defined as the set of values for which the function is defined. As we prove that the function is Many to One and Into. Hence we can say that the function is Into function. Let’s check both the conditions are satisfied or not.Īs we check that the range of function is not equal to codomain of the function. Range =, so the function is Many to One.Īs we know the condition for Into function is that the Range of function should be the subset of codomain and also not equal to codomain. The domain, codomain, and range of the above function are Remember the element which is mapped only will be counted in the range as shown in the image. The image demonstrates the domain, co-domain, and range of the function. Role of Mahatma Gandhi in Freedom Struggle.
