Please help me with these two algebra questions. Image attached.
1 answer:
1. when x⇒∞, y=∞ and when x⇒-∞, y=-∞
So, we have a odd degree polynomial (x³ or or even
).
The leading coefficient is negative its end behavior matches x³ which has a positive leading coefficient.
2. when x⇒∞, y=∞ and when x⇒-∞, y=∞
So, we have a even degree polynomial (x² or or even
).
And because it matches these parent functions listed above (they all have positive leading coefficients), the leading coefficient is again positive.
answers:
1. odd and positive
2. even and positive

1. If Sheryl works 6.5 hours in a day, she makes approximately 85 currency.
2A. If Sherly had not worked for a single hour, she would get no money.
If she worked for 1 hour, here wage would approximately be equal to 13 currency.
If Sheryl works 9 hours she will make approximately 117 currency.
Step-by-step explanation:
Step 1:
To calculate how much Sheryl makes if she works 6.5 hours a day, we check the graph to see what the y value of the graph is when .
When , the line falls on
So if Sheryl works 6.5 hours in a day, she makes approximately 85 currency.
Step 2:
The two points on the graph are at (0, 0) and (1, 13).
This means that if Sherly had not worked for a single hour, she would get no money.
If she worked for 1 hour, here wage would approximately be equal to 13 currency.
These two statements explain the two points on the graph.
Step 3:
To calculate how much Sheryl makes if she works 9 hours, we must create an equation that represents how much money she makes.
If she earns approximately 13 currency an hour, her wage is , where x is the number of hours worked and y is the wage.
When ,
So if Sheryl works 9 hours she will make approximately 117 currency.
