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].

correct answer:

i^31 = -i

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
