maybe, maybe not.
Step-by-step explanation:
The first box would be 2 and the second box would be 11.
49-65=2(3-11)
-16=2(-8)
-16= -16
Well first you need to make a graph and add how many months on the side and multiply until you get to the according amount of months hope this helps
Answer:
Hmmm let me solve then I will answer
Answer:
Step-by-step explanation:
a.) When you have the following equation
To find the vertex you take the h value, change its sign (to positive in this case) and that will give you the x value. To find the y-value just take the z. This gives us (15,-100)
b.) The axis of symmetry is just the x value of the vertex which is 15
c.) I'm not too sure what this means but can tell you that it's concave up because there's no way x can be negative
d.)Because the a value is positive that means that the graph is concave up which means that it has a minimum. The minimum is just the y value of the vertex which is just -100
e.) I'm going to write this in interval notation. The domain is all the possible x values of the graph which is all real numbers or (-∞,∞). The range is all the possible y values. We know that the minimum is -100 which means all the possible y values are [-100,∞)
f.) This is obviously a parabola and because the graph is concave up and has a negative minimum there must be 2 x intercepts.
