In the function y+2=1/3(x-4)^2
, what effect does the number 4 have on
the graph, as compared to the graph of y=x"?

The negative 4 translates the original function 4 units horizontally to the right

Step-by-step explanation:

The transformed graph is  

and the parent function is  

We need to find what effect does the "4" in the transformed function have with respect to the parent function. Lets look at a general form of a transformed quadratic function and see what each variable means:

This is the general form.

In our transformed graph, we have a "-4", this means, according to the rules above, that:

the parent function is shifted 4 units to the right

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

there is no grid
