Answer:
Parent function
Step-by-step explanation:
Parent function is a function simplest in form, of a family of functions that preserves the definition of the entire family.
We can say for example
y =sinx the parent function for all the functions given below
y = sinx +2 (Vertical shift of parent funciton by 2 units up)
y = 3 sinx (Shrink vertically by scale factor of 3)
y = 3 sin (x+1) (Horizontal shift of parent funciton by 1 unit to the right)
Thus we have the parent function is the simples function and the family of functions are got by some transformations of parent functions.
