Default Filter modulation frequency scaling

I feel like this should be straightforward but Iím not getting my head around it! I have a filter and a bipolar LFO. I want the LFO to modulate the cutoff frequency in a way that scales to the cutoff frequency, as it modulates much more deeply when the cutoff is at lower frequencies.

I think I need to translate the LFO modulation, but Iím getting a bit confused with power functions etc.

My LFO is ranging from -1 to 1 and the filter cutoff from 0 to 1. I can translate these to frequency values and back again.

I'd post my code, but it's a mess from trying things out!
