Respuesta :
Parent functions has a domain and range of all real numbers is a Cubic function
Given :
We need to find the parent function that has a domain and range of all real
numbers.
Domain is the set of all x values and range is the set of y values.
For any cubic function there is no restriction for x
For each value of x there is a y value
So, domain and range of cubic function is set of all real numbers
For reciprocal function , there will be x in the denominator . So there will be some restriction for x.
For any quadratic function , domain is set of all real numbers. For quadratic we get U shaped graph . It means there is some restriction for y.
So range cannot be real numbers
For absolute value function , we get V shaped graph . so there is some restriction for y. Range cannot be all real numbers.
