Find the domain of the function. $$ f(x)=\log _{10}(x+3) $$
Use a graphing device to find all solutions of the equation, rounded to two decimal places. \(4^{-x}=\sqrt{X}\)
Population of California The population of California was 29.76 million in 1990 and 33.87 million in 2000 . Assume that the population grows exponentially. (a) Find a function that models the population \(t\) years after 1990 . (b) Find the time required for the population to double. (c) Use the function from part (a) to predict the popuble. California in the year 2010 . Look up California's actual population in 2010 , and compare.
Find the functions \(f \circ g\) and \(g \circ f\) and their domains. $$ f(x)=\log _{2} x, \quad g(x)=x-2 $$
Draw the graph of the function in a suitable viewing rec- tangle, and use it to find the domain, the asymptotes, and the local maximum and minimum values. $$ y=\ln \left(x^{2}-x\right) $$
