Question

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

Answer 1

Switch the X and Y, then solve for y xD So x=3y-5.

Answer 2

x+5=3y......... Divide by 3.... x+5/3=y

Answer 3

\[\frac{ x+5 }{ 3}=y\]

Answer 4

g-1(x) = inverse
g(x) = 3x-5
Let g(x) = y
y = 3x-5
x = 3y-5
x+5 = 3y
(x+5)/3 = y
therefore, g(x)^-1 = (x+5)/3
