Step-by-step explanation:
<u>Exponential Function</u>
The exponential function can be written with the general equation:
Where A is the value when x=0 and r>0 is the ratio. If r is greater than 1, the function is increasing, if r is less than 1, the function is decreasing.
The table shows the relation between values of x and values of the function y. Note that as x increases (one by one), y decreases with a ratio of 1/2. Only the last two choices have ratios of r=1/2. We only have to test which one of them has the correct value of y=4 when x=0.
Substituting in the third function:
This gives the correct value of f(0)=4.
Substituting in the fourth function:
This choice is wrong
Correct choice:
I cant tell if the problem wasn’t writing correctly when u said “sarah and get 2 friends?”
i think you might of meant sarah and ___ get two friends?? please correct me but if it was meant to have another name after sarah then this would be the answer:
There was 54 original pieces
Answer:
-1/4
Step-by-step explanation:
The slope is -1/4
to solve you subtract the x-values and the y-values and remember that slope is y/x
Hope that helps and have a great day!
Answer:
A’(-5,5)
Step-by-step explanation:
x’ = 2.5 * -2 = -5
y‘ = 2.5 * 2 = 5
The domain of the original function is:
Domain: {1,2,3,4}
The range of the original function is:
Range: {2,4,6,8}
The inverse of the function f (x) is that function that fulfills:
1) The domain of f(x)^-1 is the range of the function f (x)
2) The range of f(x)^-1 is the domain of the function f (x)
We have then that the domain of the inverse function is:
Domain: {2,4,6,8}
The range of the inverse function is:
Range: {1,2,3,4}
