Thread: Graph of the Related Function

I need help solving this problem, can anyone do a step by step guide on how to do this?

1) Use the graph of the parent function to describe the graph of the related function.

F(X) = X^2 --> F(X) = 1/3 (X-1)^2 - 2

describe it, as in words?

the -1 shifts the parent function 1 horizontally, 1 unit to the right.
the 1/3 shrinks this shifted function by a factor of 3
finally, the -2 shifts this function vertically down 2 units

Thanks, now how about this one.

F(X) = -(square root of 2) - 3

that question is incomplete, where is the parent function? where is the new function? did you notice you only have a constant there? there's no x

Ohh, oops I am having too much stuff to study; I dint notice.

F(X) = (square root of X) --> F(X) = - (square root of X) - 3

if then .

how do you think we shifted the old graph to get the new one?

Here are the graphs.
