These are hard. I need help!!

a) downwards

b) (1,9)

c) x intercepts=-2, 3

y intercept= 8

d)  axis of symetry= x=1

Step-by-step explanation:

the axis of symetry is the x value of the vertex of the parabola, which is the highest point on the graph.

It opens downward because the open part is on the bottom

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
