Lopez Unit 2B Review

Front

What is the transformation of the function y = -3x^2 from the parent function y = x^2?

Back

Reflection over x-axis and vertical stretch by 3.

Front

What is the equivalent function of h(t) = -16t^2 + 32t + 4?

Back

h(t) = -16(t - 1)^2 + 20.

Front

What is the vertex of the parent function y = x^2?

Back

(0, 0)

Front

How does a function transform if it is compressed?

Back

The graph becomes narrower.

Front

What happens to the graph of f(x) = ax^2 if 0 < a < 1?

Back

The graph becomes wider or vertically compressed.

Front

What does a reflection over the x-axis do to a function?

Back

It flips the graph over the x-axis.

Front

What is a vertical stretch in a quadratic function?

Back

It makes the graph narrower and increases the y-values.

Front

What is the effect of a vertical shift down in a function?

Back

It moves the graph downward by a certain number of units.

Front

What is the standard form of a quadratic function?

Back

y = ax^2 + bx + c.

Front

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

Back

It determines the direction and width of the parabola.
