If this function is shifted 4 units to the right, then the resulting function g(x) is related to the parent function by: From the attachment, we can see that g(x) is actually 4 units to the right of f(x). If no cell is specified, returns the parent of the current cell. The concept of parent function is less clear for polynomials of higher power because of the extra turning points, but for the family of n-degree polynomial functions for any given n, the parent function is sometimes taken as xn, or, to simplify further, x2 when n is even and x3 for odd n. Turning points may be established by differentiation to provide more detail of the graph. We have step-by-step solutions for your textbooks written by Bartleby experts!
