Graphing a Function Intervals

Which is a relative maximum?

• -2.12

• 0.786

• There is none

• 4.061

How many extrema are there in this graph?

• 2 max, 2 min

• 3 max, 2 min

• 2 max, 3 min

• 3 increasing intervals, 2 decreasing intervals

• 2 increasing intervals, 3 decreasing intervals

In section A, the graph is

• Increasing

• Decreasing

• Constant

Which is the interval of increasing for the graph? Assume there are arrows on the graph.

• (-∞, 1)

• (1, ∞)

• (-∞, ∞)

• (1, 5)

Answer explanation

Look for where the graph is going UP. Base the interval on the x-values. If there is an arrow pointing left, it goes back to negative infinity. If there is an arrow pointing right, it goes to positive infinity.

Which statement is true about this function?

• The function is never constant

• The function is always increasing

• The function is never decreasing

• The function increases on the interval 11:00 < x < 15:00
