Dec Quarterly Assessment Review

Front

What is the range of a graph?

Back

The range of a graph is the set of all possible Y-values (outputs) that a function can produce.

Front

How do you determine the range from a graph with endpoints (-5, 0) and (6, -9)?

Back

The range is from the lowest Y-value to the highest Y-value, which is -9 ≤ y ≤ 0.

Front

What does the inequality y ≥ 4x - 5 represent graphically?

Back

It represents a region above the line y = 4x - 5, including the line itself.

Front

How do you find a solution to an inequality?

Back

A solution to an inequality is a point that satisfies the inequality, meaning it lies on the line or in the shaded region.

Front

What is the initial amount in a savings account if it increases by $50 each week?

Back

The initial amount is $100.

Front

What does the term 'zero of the graph' mean?

Back

The zero of the graph, or x-intercept, is the point where the graph crosses the x-axis (y=0).

Front

How do you find the intersection point of two equations?

Back

Graph both equations and identify the point where they intersect; this point is the solution to the system.

Front

What is the solution to the system of equations y = -x + 4 and y = 2(x + 2)?

Back

The solution is the point (0, 4).

Front

What is the significance of the x-intercept in a graph?

Back

The x-intercept indicates the value of x when y equals zero, showing where the graph crosses the x-axis.

Front

How do you graph the equation y = 4x - 5?

Back

Start by plotting the y-intercept (0, -5) and use the slope (4) to find another point.
