Chapter 3: Q. 28 (page 137)

In Problems 21–28, determine whether the given function is linear or nonlinear. If it is linear, determine the equation of the line .
x $y = f (x)$
-2 0
-1 1
0 4
1 9
2 16

Short Answer

Expert verified

The function is non linear.

Step by step solution

Step 1. Given Information

The given data is

x	$y = f (x)$
-2	0
-1	1
0	4
1	9
2	16

The data in the table represent values ofy with respect tox.

Compute the average rate of change of each function.

If the average rate of change is constant, then the function is linear.
If the average rate of change is not constant, then the function is nonlinear.

Step 2. Calculation

Calculate average rate of change by the formula $\frac{∆ y}{∆ x} = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

x	y	$\frac{∆ y}{∆ x}$
-2	0	1
-1	1	3
0	4	5
1	9	7
2	16

Step 3. Conclusion

The average rate of change is not constant, so the function is not linear.
