I[P] = {(d1, d2),(d2, d3)} Open Sentences: A triangle has n sides. Where does the function cross the x and y axes? Interpreting a mathematical function means obtaining meaningful information from a line graph or given symbolic representation. Why is the sentence $∀x∀y∀z((P(x, y) ∧ P(y, z)) → P(x, z))$ [call it : (A)] false in the said interpretation ? To turn the -8 into a -2 we must divide by 4, which will impact the entire equation, producing: When you're working with a function definition, you usually want to interpret the behavior of the equation or description in a visual form, such as a line graph. See more. Here we are using the = sign which indicates a balance of both sides. first two years of college and save thousands off your degree. Having found in the interpretation some values for $x,y,z$ that "falsify" the formula (B), we have shown that it is not true for all possible values, and thus the formula (A) is false in that interpretation.
