1.
What effect does replacing x with x + 2 have on the graph for the function f(x)?
f(x)=|x−3|+2
The graph is shifted 2 units right.
The graph is shifted 2 units down.
The graph is shifted 2 units left.
The graph is shifted 2 units up.

Which quadratic function best fits this data?
x y
1 350
2 539
3 678
4 875
5 690
6 502
Options:
y=−56.80x^2+437.91x+65.5
y=56.80x^2−437.91x+65.5
y=−56.80x^2−437.91x+65.5
y=−56.80x^2+437.91x−65.5

This question is basically asking what is the shift of f(x)=x+2. The answer to that is 2 to the left.
C
2)
If you have a TI-84 or 83, you can plug in the numbers into the list then make it visible on a graph. Plug in the equations one by one to see which one fits.
\(y=−56.80x^2+437.91x−65.5\) is probably your best bet
