3. Substitute 2 for yin one of the original equationsand Functionsand solve for x:In addition to being able to solve for f(x) and makex– 2y= 9judgments regarding the range and domain, you shouldx– 2(2) = 9also be able to analyze the graph of a function and inter-x– 4 = 9pret, qualitatively, something about the function itself.x– 4 + 4 = 9 + 4Look at the x-axis, and see what value for f(x) cor-x= 13responds to each xvalue.
