# Writing Truth Table Given Function

so I am taking a summer course and the teacher is not so helpful at the moment so I was thrown the following question to do:

Derive a truth table for the following function: $$\f(x,y,z)=\sum m(1,3,5,7)\$$

I dont know how to interpret the equation to make the truth table which is why I am stuck. The next two questions are to derive the sum of products & products of sum of the expression $$\f\$$ but I think I can find that out when I get the truth table (just by learning on my own)
