Question

(a) Write an equation for a graph obtained by vertically stretching the graph of $y=x^{2}$ by a factor of $2,$ followed by a vertical upward shift of 1 unit. Sketch it. (b) What is the equation if the order of the transformations (stretching and shifting) in part (a) is interchanged? (c) Are the two graphs the same? Explain the effect of reversing the order of transformations. (GRAPH CAN'T COPY)
