On a coordinate plane, a parabola opens down. it goes through (negative 1.9, negative 4), has a vertex of (0.5, 3.2), and goes through (3, negative 4). consider the graph of the quadratic function. which interval on the x-axis has a negative rate of change? –2 to –1 –1.5 to 0 0 to 1 1 to 2.5

[1, 2.5]

Step-by-step explanation:

A rate of change  on x- axis is defined as positive if the function increases as x does, and defined negative if y decreases as x increases.

Thus, we only need to see in which of those intervals [–2, –1] ,  [–1.5, 0],  [0, 1]. [1, 2.5] the graph of the function goes only down if we look it from left to right.

The only one interval satisfying this condition is [1, 2.5].

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
