You are right....it doesn't make sense

jake has 4     rudy has 3 times this much = 12      total = 16 dollars

Something is wrong with the question.......!

log₂ (x-10) = (- 11 + 9 ) / 8  = -1/4

x-10 = 2^-1/4

x = 2^-1/4  + 10 =   1 / 2^1/4  + 10  = 10 .840896

f (gx) =    3 (2x+8) + 4

            = 6x + 28 

y = 6x+28    now switch the x's and y's

x = 6y + 28     now solve for 'y' and you will have the inverse of h(x)

I think it would be this

     5     7     11

13

2

3                                because you want 13 multiplid by the largest numbers to get the largest result ......let me know if I am incorrect !

First , put -2 into the equation for 'x'    then solve......Take your result and put it back into the equation and solve again.....

y = 4 - 8x       switch the x's and y's

x = 4-8y           now solve for y

8y = 4-x

y = (4-x)/8    <===== this is the inverse fxn

Re arrange to

h^2 + h  -72 = 0      factor  ( or use  use Quaratic formula )

(x-8 )(x+9 ) = 0       can you take it from here ?       <=====remember you are only looking for h>0 answers

Nice work, catmg !
