Answer:
f^-1(x) = x - 2
Step-by-step explanation:
To find the inverse of a function in terms of x and y, you would sway x and y in the function. We can rewrite f(x) = x + 2 as y = x + 2, since f(x) is basically y in a function. The inverse of y = x + 2 would be x = y + 2. Now, solve for y.
x = y + 2
-2 both sides.
x - 2 = y
y = x - 2
The inverse of y = x + 2 would be y = x - 2, so the inverse of f(x) = x + 2 would be f^-1(x) = x - 2 (f^-1(x) means the inverse of f(x)).
f^-1(x) = x - 2
I hope you find this helpful. :)
I might be wrong but I think it's 504
I got this by multiplying 28 and 18 hope it helped : )
Answer:
Step-by-step explanation:
5(p/100)=3 multiply each side by 100
5p=300 divide each side by 5
p=60%
C. The time the car is owned is greater than 0
Function:
Where x denotes years
y denotes annual cost
We are given that the graph of the given equation should have vertical asymptote at x =0
Refer the attached graph .
Since with increase in the time the cost (y) decreases
So, the time must be greater than 0 So, that the change in the cost appears .
So, the graph of the given equation should have vertical asymptote at x =0 because The time the car is owned is greater than 0.
Hence Option C is correct : The time the car is owned is greater than 0.
Answer:
Decrease of 63.5%.
Step-by-step explanation:
Exponential function:
An exponential function has the following format:
In which y(0) is the initial value and r is the rate of change, as a decimal. If r is positive, it is a increase. If it is negative, it is a decrease.
In this question:
We have that:
So
So a decrease of 63.5%.
