Front

What is the Range of the function f(x) =−x + 7 if the Domain is {− 3, -1, 0, 2, 4}?

Back

{3, 5, 7, 8, 10}

Front

Which system of inequalities is represented in the graph?

Back

2x - y ≥ -2, x - y < 2

Front

Find the vertex of f(x) = -x² - 4x + 12.

Back

(-2, 16)

Front

What is the definition of a function?

Back

A relation where each input has exactly one output.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the quadratic formula?

Back

x = (-b ± √(b² - 4ac)) / (2a) for ax² + bx + c = 0.

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, as x increases, f(x) also increases.

Front

What is the vertex form of a quadratic function?

Back

f(x) = a(x - h)² + k, where (h, k) is the vertex.

Front

What is the difference between a linear function and a quadratic function?

Back

A linear function has a constant rate of change (straight line), while a quadratic function has a variable rate of change (parabola).
