Identifying Intervals on Which a Function Is Decreasing On a coordinate plane, a curved line with a maximum value of (negative 1
, 4) and minimum values of (negative 1.25, negative 16) and (2.5, negative 3), crosses the x-axis at (negative 2.1, 0), (0.25, 0), (1.75, 0), and (3, 0), and crosses the y-axis at (0, negative 3). Which intervals show f(x) decreasing? Check all that apply. [–2.5, –2] [–2, –1.5] [–1, 1) [1.5, 2] [2, 2.5) (2.5,
1 answer:
Answer:
[–2, –1.5]
[2, 2.5)
Step-by-step explanation:
In the figure attached, the points are shown on a coordinate plane. Also, a tentative function was drawn. It was assumed that the function is continuous.
From the picture, decreasing intervals are: [–2, –1.5] and [2, 2.5)
In intervals [–2.5, –2] and [1.5, 2] there is not enough information to know if the function is decreasing or not.
