Front

What is the average of three values: t + 4, t, and t - 2?

Back

(3t + 2) / 3

Front

What type of function is represented by a constant rate of change, such as a $5 admission fee per person?

Back

Linear

Front

How do you find the vertex of a quadratic function in the form f(x) = ax^2 + bx + c?

Back

Use the formula (-b/(2a), f(-b/(2a))). For f(x) = -x^2 - 4x + 12, the vertex is (-2, 16).

Front

What is the first step to solve the equation 11 - 3x = 44?

Back

Subtract 11 from both sides.

Front

What is the solution to the system of equations represented by the points (1, -1), (-1, 1), (0, -2), and (2, 0)?

Back

(1, -1)

Front

What is the formula for the average of n numbers?

Back

(Sum of all numbers) / n

Front

What does it mean for a function to be linear?

Back

A linear function has a constant rate of change and can be represented by a straight line on a graph.

Front

How do you determine if a function is exponential?

Back

If the function can be expressed in the form f(x) = a * b^x, where b is a constant greater than 1 or between 0 and 1.

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex represents the maximum or minimum point of the parabola.

Front

What is the process to isolate a variable in an equation?

Back

Perform inverse operations to both sides of the equation until the variable is alone.
