## Calculus 8th Edition

1. Parent function $y =f(x)=\cos x$ ( Create a table with a selection of values for x, arriving at ordered pairs (x,f(x)). Plot them and connect with a smooth curve) 2. $y=-f(2x)$ Shrink horizontally by a factor of 2, and reflect about the x-axis. Use the table (x,f(x)) to plot the points $(x, \displaystyle \ \ -\frac{1}{2}f(x)))$ and join with a smooth curve)
