Question

If g(x) = 3x - 5, then g -1(x)=

Answer 1

are you looking for the inverse of this function?

Answer 2

Assuming you are,
set up the equation,
y = 3x - 5

then switch the variables,

x = 3y - 5

then solve for y that will give you the inverse of the function

Answer 3

do you follow?

Answer 4

no not really sorry

Answer 5

you are simply switching the input (x) and output variable (y), this can only be done with functions that obey the horizontal rule

The horizontal rule being, the ability to draw a line horizontal through the graph of the function without it passing through the function more than once.

Passes the horizontal line test


Fails the horizontal line test (the line passes through the function more than once)
