Use the graph of ƒ (x) = x² below to find a number & such that | x² - 1| - < 0.2 whenever 0 < |x − 1| < §. - 1.2 y 1 0.8 Round your answer to four decimal places. δ = Number 1

Sketch the graph of each piece-wise defined function; show all work.

Graph the function  f(x) =3 · 2x.  Use the graph to determine the y-values at x-values of −2, −1, 0, 1, and 2. For every increase of 1 in the x-value, the y-value can be found from the previous y-value by multiplication of a constant. The constant is equal to   .
