What is the cost per linear foot of vinyl fencing if the installation fee is flat and the total cost is represented in a graph?

Back

$15

Front

What is a rational number?

Back

A rational number is any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.

Front

What does a higher rate of change in a graph indicate?

Back

It indicates that the quantity is increasing or decreasing at a faster rate compared to another representation.

Front

What is the minimum value of a quadratic function?

Back

The minimum value of a quadratic function is the lowest point on its graph, which occurs at the vertex if the parabola opens upwards.

Front

How do you solve the equation 3x + 1 = x + 5?

Back

Subtract x from both sides to get 2x + 1 = 5, then subtract 1 from both sides to get 2x = 4, and finally divide by 2 to find x = 2.

Front

What is the formula for the slope of a line?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What is a quadratic function?

Back

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

Front

What does it mean for a function to be increasing?

Back

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

Front

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

Back

A linear function has a constant rate of change and graphs as a straight line, while a quadratic function has a variable rate of change and graphs as a parabola.

Front

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

Back

The vertex represents the maximum or minimum point of the parabola, depending on its orientation.
