According to the video, what is the appoximated slope to the tangent line shown?

• 1.4175

• 1.33875

• 2.75625

• 0

Why is the rate of change of point B negative?

• Because the graph is decreasing

• Because the graph is increasing

• Becasue the graph is concaving downwards

• Because the graph is concaving upwards

Why does the rate of change decrease from point A to point B

• Because the graph is concaves down

• Becasue the graph concaves up

• Because the graph is increasing

• Because the graph of decreases

What is the rate of change at the extremas of a function?

• 0

• positive

• negative

• undefined

• D

Why does point C have a positive rate of change?

• Because the graph is increasing.

• Because the graph is decreasing

• Because the graph concaves up
