What is a linear-quadratic function?

Back

A function that combines linear and quadratic components, typically expressed in the form y = ax^2 + bx + c, where a, b, and c are constants.

Front

How do you determine the solution to a linear-quadratic function?

Back

By finding the points where the linear and quadratic equations intersect, often using methods like substitution or graphing.

Front

Simplify: -3i(4 + 2i)

Back

6 - 12i

Front

What is point-slope form of a linear equation?

Back

The point-slope form is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Front

Write the point-slope form of the line that passes through (4, -7) with slope -1/4.

Back

y + 7 = -1/4(x - 4)

Front

What is the Quadratic Formula?

Back

The Quadratic Formula is x = (-b ± √(b² - 4ac)) / (2a), used to find the roots of a quadratic equation ax² + bx + c = 0.

Front

Solve the equation using the Quadratic Formula: x² + 6x - 4 = 36.

Back

x = 4, -10

Front

What does it mean to transform an equation?

Back

Transforming an equation involves changing its position or shape on a graph, such as shifting, reflecting, or stretching.

Front

Identify the transformation: Reflect/Left 1/Down 8.

Back

This indicates a reflection across the y-axis, a left shift by 1 unit, and a downward shift by 8 units.

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers, and A should be non-negative.
