What is the RANGE of the function y = -2|x - 3| + 5?

Back

y ≤ 4 - The range is determined by the maximum value of the function.

Front

What does the graph of the function y = -2|x - 3| + 5 look like?

Back

Graph C - It is a V-shaped graph opening downwards with vertex at (3, 5).

Front

Select the correct graph for the inequality y < 2x + 3.

Back
