Answer:
Step-by-step explanation:
5). Graph of the parent function f(x) = x has been given in the picture.
To map the graph the function 'f' onto the graph of function 'g',
f(x) = x
g(x) = 4x
A vertical stretch of the function 'f' by a scale of 4 is required.
6). Rule for a function to be translated by 'a' units down,
g(x) = f(x) - a
By this rule, if the function 'f' is translated 7 units down,
g(x) = f(x) - 7
g(x) = x - 7
