Sample: the first question, solved

Describe the graph of f(x)=1/(x+3) near its vertical asymptote (x=−3).

📘 Worked solution
As x→−3⁺, f(x)→+∞; as x→−3⁻, f(x)→−∞ — two separate branches, matching the pattern of 1/x shifted left.

And one from the hard end

Find the x-intercept of f(x)=(x−4)/(x+1).
