graph of f(x)

As |a| decreases, the parabola becomes ✔ wider.narrower.flat.

graph of f(x)

Choose the graph of y = (x – 3)2 + 1.

As |a| increases, the parabola becomes wider.✔ narrower.flat.

The graph of function 1 function 2 function 3 function 4 is the widest.

If the parabola of the form y = a(x – h)2 + k is always shifted horizontally h units and vertically k units, then its vertex is always

graph of f(x)

The graph of function 1 function 2 function 3 function 4 is the narrowest.

by units.

The graph of function 2 is narrower thanwider thanthe same as the graph of function 3.

graph of f(x)

by units.

Choose the equation that shows a step in the process of completing the square on the given quadratic.y = x2 + 8x – 3

⇒ 4

The vertex form of the function is y = (x + )2 + .

When the above expression is written in vertex form, a is , h is , and k is .

When the above expression is written in vertex form, a is , h is , and k is .
