Question

1. identify key points using the graph below. max: min: leftmost: rightmost: y - intercept:

Explanation:

Step1: Locate maximum point

The highest point of the graph is at $(3,7)$.

Step2: Locate minimum point

The lowest point of the graph in the visible range is at $(-5, - 2)$.

Step3: Find left - most point

The left - most point with an open - circle is at $(-9,1)$.

Step4: Find right - most point

The right - most point with a closed - circle is at $(9,-2)$.

Step5: Find y - intercept

The graph crosses the y - axis at $(0,5)$.

Answer:

Max: $(3,7)$
Min: $(-5,-2)$
Leftmost: $(-9,1)$
Rightmost: $(9,-2)$
y - intercept: $(0,5)$
