Find f(-2) for f(x)=3×2x​

substitute every x in the equation with (-2)

f(-2)=3*2*(-2) = -12

dunno if I get your equation correctly, pls check how you have written it

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
