If f(x) = one/nine x -2, what is f^-1(x)

Mathematics

astraxan [27]3 years ago

Answer:

f^{-1} (x)=9x+18

Step-by-step explanation:

Assuming f(x)=\frac{1}{9} x-2

What we have to do is replace f(x) with y, swap the locations of x and y, and then solve for y.

y= \frac{1}{9} x-2\\\\x=\frac{1}{9}y-2\\ \\x+2=\frac{1}{9}y\\\\y=9x+18\\\\f^{-1} (x)=9x+18

Write an equation that expresses the fact that a function f is continuous at the number 4.
vesna_86 [32]
  <span>Use the definition of continuity. 
A function is continuous at a point x = a iff 
lim [x → a] f(x) = f(a) 

In other words, a function is continuous at a point if its value is equal to its limit at that point. 

So, for f(x) to continuous at x = 4 we must have 
lim f(x) = f(4) 
x → 4
