Front

What is the time taken to reach the highest point over the water in the given scenario?

Back

1 second

Front

What is the equation of a quadratic function translated up 5 units?

Back

y = x² + 5

Front

What transformation does the function g(x) = 2f(x) represent?

Back

Vertical stretch

Front

How does the graph of f(x) = x² transform to g(x) = (x + 4)²?

Back

A horizontal translation 4 units to the left

Front

What transformations are applied to the parent function for h(x) = -2x² + 1?

Back

Reflect in the x-axis, vertically stretched by a factor of 2, and translate 1 unit up.

Front

What is a quadratic function?

Back

A polynomial function of degree 2, typically in the form y = ax² + bx + c.

Front

What does it mean to translate a graph vertically?

Back

To shift the graph up or down without changing its shape.

Front

What is a vertical stretch in the context of function transformations?

Back

A transformation that increases the distance between points on the graph and the x-axis.

Front

What is the effect of a horizontal translation on a graph?

Back

It shifts the graph left or right along the x-axis.

Front

How do you identify the vertex of a quadratic function in standard form?

Back

The vertex can be found using the formula x = -b/(2a) for the function y = ax² + bx + c.
