Front

What is the accuracy range of Cameron's laser range finder if it measures 136 yards?

Back

The minimum distance could actually be 135.5 yards, as the range finder is accurate to within 0.5 yards.

Front

Which point is a solution to the equation y = 2x + 2?

Back

(1, 0) is a solution because when x = 1, y = 2(1) + 2 = 4.

Front

What is the vertex form of a quadratic function?

Back

Front

How do you find the y-intercept of a quadratic function?

Back

To find the y-intercept, set x = 0 in the function and solve for f(0).

Front

What does the graph of y > 2x - 4 represent?

Back

It represents the area above the line y = 2x - 4.

Front

What is the standard form of a quadratic equation?

Back

Front

How do you determine if a point lies on a line represented by an equation?

Back

Substitute the x-value of the point into the equation and see if the resulting y-value matches the y-value of the point.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, indicating the value of y when x = 0.

Front

What is the solution set of the inequality y < 2?

Back

The solution set includes all points below the horizontal line y = 2.

Front

How do you graph a quadratic function in vertex form?

Back

Identify the vertex (h, k), plot it, and then use the value of 'a' to determine the direction and width of the parabola.
