📝 Answered - Sanjay begins to correctly graph the function [tex]f(x)=(x+1)^2-3[/tex]. Based on the axis of symmetry and the vertex, which graph could be Sanjay's?

📝 Answered - The pattern of numbers below is an arithmetic sequence: $14,24,34,44,54, \ldots$ Which statement describes the recursive function used to generate the sequence? A. The common difference is 1, so the function is $f(n+1)=f(n)+1$ where $f(1)=14$. B. The common difference is 4, so the function is $f(n+1)=f(n)+4$ where $f(1)=10$. C. The common difference is 10, so the function is $f(n+1)=f(n)+10$ where $f(1)=14$. D. The common difference is 14, so the function is $f(n+1)=f(n)+14$ where $f(1)=10$.
