3. Let $T: P_2 \to P_2$ be the linear operator defined by $T(a_0 + a_1x + a_2x^2) = a_0 + a_1(x-1)+a_2(x-1)^2$ (a) Find the matrix for $T$ relative to the standard basis $B=\{1, x, x^2\}$ for $P_2$. (b) Verify that the matrix $[T]_B$ obtained in part (a) satisfies Formula (8) for every vector $\mathbf{x} = a_0 + a_1x + a_2x^2$ in $P_2$.

choose a specific piece of technology you use on a daily basis - a specific app (outlook, blackboard, pronto, snapchat) will work much better than a broad medium (email, internet). identify which values it claims is most important , and discuss how it highlights those values instead of others. Then, identify the values it places in standing reserve. why are those values excluded and what might you be missing by leaving them out of the frame ?

Thinking back on what you learned in calculus, you realize that your path will need to be continuous. You just need to tell your computer what the parameters below should be in order to create this continuous path. What parameters do you give your computer?\\ $f(x) = \begin{cases} 9, & x < -2 \\ -x + A, & -2 < x \le -1 \\ Bx + 8, & -1 < x \le 0 \\ -6x + C, & 0 < x \le 1 \\ Dx - 2, & 1 < x \le 2 \\ 6, & x > 2 \end{cases}$

You are planning a routine that will query a database for a sales representative's commission rate, multiply this rate by each item in a list of daily sales totals to determine the daily commissions, then sum them to determine the total commission for the month. You consider writing a loop to iterate over the list items, whose body would include statements that: (1) retrieve the commission rate from the database, (2) multiply the rate by a daily sales value, and (3) add that value to an accumulator. Additional body statements would alter the loop control variable. This loop would _____. a. never terminate b. be inefficient c. not return the desired results d. be unstructured
