The correct answer should be C
Answer:
and 
Step-by-step explanation:
To find the inverse, we will set f(x) equal to y, swap the x and y values, and then solve for y.
Given:
f(x) = x² - 25
Equal to y:
y = x² - 25
Swamp x and y values:
x = y² - 25
Add 25 to both sides of the equation:
y² = x + 25
Square root both sides of the equation:

Answer:
The value of basketball player's autograph a year ago is $280
Step-by-step explanation:
Given as :
The present value of autograph = $ 336.00
The rate of increase of autograph = 20%
The time period = 1 year
Let The value one year ago = $ x
So ,
The value of autograph after n year = The present value × 
Or, $ 336.00 = $ x × 
Or, $ 336.00 = $x × 1.2
∴ x =
= $280
Hence The value of basketball player's autograph a year ago is $280 Answer
Answer:
552.6 because 15% × 3684 = 552.6
