Answer:
Switch x and y, and solve for y
Step-by-step explanation:
Given
Required
Complete the steps to determine the inverse function
Solving (a): Complete the blanks
Switch x and y, and solve for y
Solving (b): Determine the inverse function
Replace f(x) with y
Switch x and y
<u>Now, we solve for y</u>
Subtract 4 from both sides
Take cube roots of both sides
Divide both sides by 8
So, we have:
Hence, the inverse function is:
It would be 3/2 x 3/1 which would = 4 1/2
5x + 10 10
---------- = -------
121 11
make the bottom have same common denominator
10/11 x (10/10) = 100/121
Get rid of the denominator (for both now have 121 as a base)
5x + 10 = 100
5x + 10 (-10) = 100 (-10)
5x = 90
5x/5 = 90/5
x = 18
x = 18 is your answer
hope this helps
