Solve the following inequalities, if it is known that function g is decreasing on its domain.

g (x^2) > g (5x+6), D(g) = [1,∞)

PLEASE HELP. IVE BEEN STUCK ON THIS PROBLEM FOR THE PAST HOUR.

Answer:

1 ≤ x < 6

Step-by-step explanation:

Okay so the answer is 1 ≤ x < 6, and the way you solve it is pretty simple :)

First: Eliminate the functions of the inequality, leaving it to just being an inequality. You have to understand that the function is decreasing on its domain, so the sign will reverse itself once you take away g(x)

This should take you from having [tex]g(x^{2} )>g(5x+6)[/tex]  to having [tex]x^2<5x+6[/tex]. From here you solve the inequality to get [tex]-1<x<6[/tex], although you aren't done.

Afterwards you take into account the domain, which restricts everything to being greater than or equal to one. This means that your inequality changes to 1 ≤ x < 6.

yw and good luck w ur rsm hw haha

lmk if this was helpful :P
