The interval that is a solution for the graph to be positive is; D: -∞ < x < -1
<h3>How to interpret graph intervals?</h3>
For the graph to be positive, the x-values will have to produce y-values that are always positive.
Now, from the given graph, we can see that all the x-values less than -1 produce positive values of y which makes the graph positive.
Thus, the interval that is a solution for the graph to be positive is;
-∞ < x < -1

Answer:19
Step-by-step explanation:
Answer:
A. Figures with the same shape, but not necessarily the same size
The maximum time 1.75 second in case of not having the height:
1. change in ax²+bx+c form⇆ -16t²+56t-40=h
h=(8-8t)(2t-5)
h=16t-40-16t²+40t
h=-16t²+56t-40
2. t max=-b/(-2a)=-56/(-2×-16)=1.75 second
