f(x) = 6x
To find the inverse, replace f(x) with Y:
y = 6x
Now switch the variables:
x = 6y
Solve for Y by dividing both sides by 6:
y = x/6
Now replace y with f^-1 (x):
f^-1 (x) = x/6
Answer:
$4748.80
Step-by-step explanation:
First, find the cost with 20% off, by multiplying the price by 0.8
5600(0.8)
= 4480
Find the cost with tax, by multiplying this by 1.06
4480(1.06)
= 4748.8
So, the sale price, including tax, is $4748.80
You're question asks why the given mixed numbers are equal.
In fact, they're equal.
Lets make it easier for you to understand:
8 4/3 has a improper fraction "4/3", that fraction is over 1 whole.
You could look at 8 4/3 as:
8 + 3/3 + 1/3
The 3/3 turns into 1:
8 + 1 + 1/3
9 + 1/3
9 1/3
You would see that it turns into 9 1/3, therefore they are equal.
Vertical asymptote means the equation is undefined at that point, or when the denominator is 0. Is the equation F(x)=1/x+2 or F(x)=1/(x+2)? Just set whatever's on the bottom equal to zero and solve for x.
