Question

Problem set3: Unit 2. Applications of Differentiation 2A-1 Find the linearization of root(a+bx) at 0, by using (2) <-- In this problem, which means (2)?? I don't know what this means about.....

Answer 1

Does it mean the square root? As the sentence " find the linearization of root (a+bx) at 0", it failed to tell it's a cube root or a square root.

Answer 2

JingleBells and I have the same question. The problem set keeps making reference to those numbers in parenthesis.
