- Exercises 31–38: Determine if f is a linear or nonlinear function. If f is a linear function, determine if f is a constant function. Support your answer by graphing f. -2 35. f (x) = |x + 1|arrow_forwardEvaluating a Function In Exercises 5–12,evaluate the function at the given value(s) of theindependent variable. Simplify the results.f (x) = 3x − 2 (c) f (b)arrow_forwardIn Exercises 65–68, find and sketch the domain of ƒ. Then find an equation for the level curve or surface of the function passing through the given point.arrow_forward
- Graphing Inverse Functions Each of Exercises 11–16 shows the graph of a function y = ƒ(x).Copy the graph and draw in the line y = x. Then use symmetry withrespect to the line y = x to add the graph of ƒ -1 to your sketch. (It isnot necessary to find a formula for ƒ -1.) Identify the domain andrange of ƒ -1.arrow_forwardPiecewise-Defined FunctionsGraph the functions in Exercises 25–28.arrow_forwardpart 2 c functionnal analysisarrow_forward
- Inventing Graphs and FunctionsIn Exercises 75–78, sketch the graph of a function y = ƒ(x) that satisfies the given conditions. No formulas are required—just label the coordinate axes and sketch an appropriate graph. (The answers are not unique, so your graphs may not be exactly like those in the answer section.)arrow_forwardEven and Odd FunctionsIn Exercises 47–58, say whether the function is even, odd, or neither. Give reasons for your answer.arrow_forward
