Hi everyone, I have an optimization problem of the form,

```
((x_1+x_2 ))/((2^(x_1/B)+2^(x_2/A)+y) ).
```

A and B are known constants. The variables are x_1, x_2 and y. All my inequality constraint sets are convex and equality constraint sets are affine. I strongly believe this is Quasiconvex since the numerator is affine and the denominator is a convex function.

In solving it through a sequence of convex feasibility problems, I introduce a new and additional constraint of the form,

```
(x_1+x_2 )-η(2^(x_1/B)+2^(x_2/A)+y)≤0,
```

where η is known (already solved for). Because of this new constraint I understand I cannot use CVX since

```
-η(2^(x_1/B)+2^(x_2/A)+y)
```

is a concave function and not convex. Now my question; please is there anyway that I can express this additional constraint in a convex form??

Thank you.
