Front

Factor the expression: a^2 - a - 12

Back

The factored form is (a - 4)(a + 3).

Front

What does it mean to stretch a graph vertically by a factor of k?

Back

Stretching a graph vertically by a factor of k means that every y-coordinate of the graph is multiplied by k, making the graph taller.

Front

What is the difference between compression and stretching in transformations?

Back

Compression reduces the size of the graph, while stretching increases it. Both can occur vertically or horizontally.

Front

How do you factor a quadratic expression of the form ax^2 + bx + c?

Back

To factor, find two numbers that multiply to ac and add to b, then rewrite the expression using these numbers.

Front

What is the distributive property in algebra?

Back

The distributive property states that a(b + c) = ab + ac, allowing you to multiply a single term by multiple terms inside parentheses.
