The answer is that f-1(3) = 7.
In order to find the answer, we first must find the inverse function. The f-1 indicates that we are looking for an inverse. To find any inverse, we first must switch the x and f(x) values. We then solve for the new f(x), which gives us the inverse.
f(x) = (2x - 2)/4 ----> Switch x and f(x)
x = (2f(x) - 2)/4 -----> Multiply both sides by 4
4x = 2f(x) - 2 ----0-> Add 2 to both sides
4x + 2 = 2f(x) ------> Divide both sides by 2
f-1(x) = (4x + 2)/2
Now that we have the inverse function, we can put in 3 and find the answer.
f-1(x) = (4x + 2)/2
f-1(3) = (4(3) + 2)/2
f-1(3) = (12 + 2)/2
f-1(3) = (14)/2
f-1(3) = 7
Step-by-step explanation:
Set up the division problem in long division format.
Divide 16 by 3
. Place this digit in the quotient on top of the division symbol. Multiply the newest quotient digit (5) by the divisor
Subtract 15 from 16
The result of division of 163 is 5 with a remainder of 1
- Use the long division solution to convert the original fraction (163)
- to a mixed number. The whole number portion of the mixed number will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction (5), and the fraction portion of the mixed number will be the remainder of the original fraction division (1) over the denominator of the original fraction (3)
