(a)
Find the parent function
(a)
Answer to Problem 39E
For the function
Explanation of Solution
Given information:
Calculation:
Parent function is the basic function of a family of functions that preserves the definitions, shape of its graph and properties of the entire family.
Parent function used in this question is the absolute value function i.e
To identify the parent function, strip all the arithmetic operations on the function to leave behind one higher order operation in just x.
So, remove the arithmetic operation of multiplication by -1 and then addition of 4 to x and addition of 8 to it from the given funcion to get the parent function.
Conclusion:
So,
remove the arithmetic operation of subtractionof 1 from x and multiplication by -2 and then subtraction of o
f 4 from the given funcion to get the parent function.
Find the sequence of transformation from f to g.
