Question

The rule for G^-1(x) in G(x)=3x-5/4 is G^-1(x) =

A.(4x-5)/3
B.(4x+5)/3
C.(3x+5)/-4

Answer 1

write G(x) = y
and then solve for x like
y = 3x-5/4
solve for x now

Answer 2

if y = 3x-5/4
then x =???

Answer 3

SO do you just change the signs?

Answer 4

no the whole equation changes

Answer 5

ok look
y = 3x-5/4
y+3/4 = 3x
can you find x now??

Answer 6

ok look
y = 3x-5/4
y+5/4 = 3x
now find x
