Image not showing well on mobil

I have a background image near the bottom of my home page that says “Health – Consciousness – Wellbeing”.

It shows up just fine when I am on my laptop, but when I view it from either of my mobile devices, no matter which way I hold the screen, the right and left sides of the image are cut off.

Is there a way for me to downsize the image just for mobile devices so the whole thing shows up?
