Use the graph to estimate the specified limit.Find 
f(x)
A. does not exist B. 1 C. -1 D. 0
Determine whether the graph opens upward or downward.y = -2x2 + 12x - 22
A. Upward B. Downward
First, rewrite each equation in exponential form. Then, use a table of coordinates and the exponential form to graph the logarithmic function. Begin by selecting -2, -1, 0, 1 and 2 for y. Finally, based on your graph, describe the shape of a scatter plot that can be modeled by f(x) = log b x, 0 < b < 1.y = log1/2 x
