I'm not sure how to answer this question. could someone explain it? use the graph of the parent function, f(x)=sqrt x, to describe the transformation for the graph of g(x)=sqrt x-5 a. the graph of g(x) is the graph of f(x) shifted up 5 units b. the graph of g(x) is the graph of f(x) shifted down 5 units c. the graph of g(x) is the graph of f(x) shifted right 5 units d. the graph of g(x) is the graph of f(x) shifted left 5 units. i think the answer should either be down 5 or right 5 but i still don't quite understand. you!

Consider the parent function, . 

The function f, takes a number x, and produces the square root of it, for example we have the points:

(1, 1), (4, 2), (25, 5), (100, 10).

The function , takes a value x, subtracts it 5, and then produces the square root of this difference.

So to produce the values 1, 2, 5, 10 given in the previous function, we need to 

plug in the function not 1, 4, 25, and 100, but 6, 9, 30, 105.

Comparing  : (1, 1), (4, 2), (25, 5), (100, 10) of (x, f(x)) with 

                      (6, 1), (9, 2), (30, 5), (105, 10) of (x, g(x)),

we see that the graph of g is the same as the graph of f shifted 5 units right.

In general, the graph of  y=f(x-a), where a is a positive number, is the graph of y=f(x) shifted a units right.

Well if you have 20 bats you probably want 20 balls? you don’t have enough context to answer the question.
