Question

f g(x) = 3x + 5, what is g–1(x)?

Answer 1

3x+5= -1 SO that means x=6

Answer 2

If im correct it should :)

Answer 3

g^-1 if any one finds that confusing

Answer 4

if?
\[g^{-1}(x)=\frac{x-5}{3}\]
original function says "multiply by 3, add 5"
inverse says "subtract 5, divide by 3"

Answer 5

like if you were solving
\[3x+5=17\] you would subtract 5 and get
\[3x=12\] then divide by 3 and get
\[x=4\]
that is what the inverse function does, take you back to where you started from

Answer 6

ok , well thats what i got but the way ur explaining it confuses me

Answer 7

g(x)let=y
y=3x+5
x=3y-5
3y=x-5
3y/3=x/3-5/3
y=x/3-5/3
g(x)=x/3-5/3
