Question 1 (1 point) ✔ Listen The nativists' position on language development is supported by the finding that children learn the language that their parents speak, down to the regional accent. children whose caregivers frequently encourage them to converse by asking * questions are more advanced in early language development than those whose parents are less conversational. children all progress through the same language sequences at roughly similar ages and even make the same kinds of errors. young children are highly responsive to the feedback they receive, making vocalizations that are rewarded more frequently than those that receive no response.

Differentiate the following with respect to \( x \) i. \[ 3 x y^{2}+5 x+y^{2}+\frac{y}{x^{2}}=0 \] ii. \[ y=\frac{(x+2)^{2}(x-3)}{(\sqrt{2 x+5})(2 x+7)^{4}} \] \[ y=x^{x} \] iii. b. Find the limits of the following i. \[ \lim _{x \rightarrow \infty} \frac{5 x^{3}-4 x^{2}+5 x+2}{x^{3}-10} \] ii. \[ \lim _{x \rightarrow 1} \frac{\sqrt{x+5}-3}{x-4} \]
