Front

What transformation shifts the graph of f(x) = x^2 to g(x) = (x + 4)^2?

Back

The transformation shifts the graph 4 units to the left.

Front

Solve for z: 11z - 5 = 9z + 7

Back

z = 6.

Front

Find the vertex of the function f(x) = -x^2 - 4x + 12.

Back

The vertex is (-2, 16).

Front

Does the graph of y = 5(x - 5)^2 + 3 widen or narrow from the parent function?

Back

The graph narrows.

Front

What is the standard form of a quadratic function?

Back

Front

What does the 'a' value in a quadratic function determine?

Back

The 'a' value determines the direction of the parabola (upward if a > 0, downward if a < 0) and its width.

Front

How do you find the axis of symmetry for a quadratic function?

Front

What is the effect of changing the 'c' value in a quadratic function?

Back

Changing the 'c' value shifts the graph up or down without affecting its shape.
