Use the dot product to determine whether v = 2i + 8j and w = 4i - j are orthogonal.

Write down the 4 by 4 matrix S that scales by a constant c. Multiply ST and also TS, where T is translation by (1, 4, 3). To blow up the picture around the center point (1, 4, 3), would you use vST or vT S?

Consider the function y=-2(1/2(x-1))^2+5.    Find the x and y-intercepts. Round to one decimal place where necessary.  i)  State the mapping notation formula.   ii)  Transform the key points of y=x^2 using mapping notation.  i) (x/k + d, ay + c)  Graph the function using a) and b) above.
