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.

2.

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

1)

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
