What is a strong negative correlation in a graph?

Back

A strong negative correlation indicates that as one variable increases, the other variable decreases significantly.

Front

Write the equation representing the relationship between months opened (x) and total membership (y) if a fitness club starts with 80 members and gains 15 members each month.

Back

y = 15x + 80

Front

Factor the expression x² - 16.

Back

(x - 4)(x + 4) - This is a difference of squares.

Front

What can be concluded if ƒ(x) = -2x² - 8x + 20 has a greater maximum than g(x)?

Back

ƒ(x) has a higher peak value compared to g(x), indicating it reaches a higher maximum point.

Front

Expand the expression (4x + 1)(5x - 2).

Back

20x² - 3x - 2.

Front

What is the definition of a quadratic function?

Back

A quadratic function is a polynomial function of degree 2, typically in the form f(x) = ax² + bx + c.

Front

What does it mean for a function to have a maximum?

Back

A function has a maximum when it reaches its highest point over a given interval.

Front

What is the vertex of a parabola represented by the equation y = ax² + bx + c?

Back

The vertex can be found using the formula (-b/(2a), f(-b/(2a))).

Front

What is the difference between a strong positive correlation and a weak positive correlation?

Back

A strong positive correlation indicates a close relationship where both variables increase together, while a weak positive correlation shows a less consistent relationship.

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.
