Answer:
The domain and range remain the same.
Step-by-step explanation:
Hi there!
First, we must determine what increasing <em>a</em> by 2 really does to the exponential function.
In f(x)=ab^x, <em>a</em> represents the initial value (y-intercept) of the function while <em>b</em> represents the common ratio for each consecutive value of f(x).
Increasing <em>a</em> by 2 means moving the y-intercept of the function up by 2. If the original function contained the point (0,x), the new function would contain the point (0,x+2).
The domain remains the same; it is still the set of all real x-values. This is true for any exponential function, regardless of any transformations.
The range remains the same as well; for the original function, it would have been 
. Because increasing <em>a</em> by 2 does not move the entire function up or down, the range remains the same.
I hope this helps!

Step-by-step explanation:
79×0.08 = 6.32 (tax)
79(price) + 6.32(tax) = 85.32
Answer: 8
Step-by-step explanation: the given expression is 2n-3
so when n=1, we will get, 2(1)-3=2-3=-1
when n=2, we will get, 2(2)-3= 4-3=-1
when n=3, we will get 2(3)-3= 6-3=3
when n=4, we will get 2(4)-3 = 8-3=5
so the required result of expansion is -1+1+3+5=8
answer is 8.
hope that helped!
Answer:
110.386
Step-by-step explanation:
what you have to do is take 20% of 142.25 (which you can do by looking it up or multiplying 142.25 by 20 and then multiplying that by .1) then you find 3% of that and add the 3% (by using the steps i gave you for the 20%)
