This graph has a horizontal asymptote so it is an exponential graph. It also passes through two points (0,-2) and (1,3). The horizontal asymptote is at y=-3.
The unchanged exponential equation is y=a(b)^x +k
For exponential equations, k is always equal to the horizontal asymptote, so k=-3.
You can check this with the ordered pair (0,-2). After that plug in the other ordered pair, (1,3).
This gives you 3=a(b)^1 or 3=ab. If you know the base the answer is simple as you just solve for a.
If you don't know the base at this point you have to sort of guess. For example, let's say both a and b are whole numbers. In that case b would have to be 3, as it can't be 1 since then the answer never changes, and a is 1. Then choose an x-value and not exact corresponding y-value. In this case x=-1 and y= a bit less than -2.75. Plug in the values to your "final" equation of y=(3)^x -3.
So -2.75=(3^-1)-3.
3^-1 is 1/3, 1/3-3 is -8/3 or -2.6667 which is pretty close to -2.75. So we can say the final equation is y=3^x -3.
Hope this helps! It's a lot easier to solve problems like these given either more points which you can use system of equations with, or with a given base or slope.
Answer:
1. Co - payment
2. Coinsurance
3. Deductible
Step-by-step explanation:
1. Deductible:
A certain amount that you pay before the insurance company pays a claim.
2. Coinsurance:
The percentage of the cost that you share with the insurance company
3. Co-payment:
A fixed amount that you pay the provider at the time of service. {Usually, a standard procedure in Health Insurance.]
Answer:
The answer is B.
Step-by-step explanation:
r- (-12.4) = -15.8
r + 12.4 = -15.8
-12.4 -12.4
r = -28.2
Answer:
85
Step-by-step explanation:
To solve this, you would have to figure out what 80% of 106 is. 80% of 106 is 84.8. If you were to round this to the nearest whole number, you would get 85.
