# In Exercises 19-24, graph the given functions. Give the technology formula, and use technology to check your graph. We suggest that you become familiar with these graphs in addition to those in Table 1. [HINT: See Quick Example 4.) f ( x ) = x + 1 x     ( x ≠ 0 )

To determine

To graph: The function f(x)=x+1x(x0) and a technology formula and use technology to check its graph.

Explanation

Given Information:

The provided function is:

f(x)=x+1x(x0)

Graph:

The function is represented by the symbol f and x represents different values for which the function gives different values.

Consider the following function.

f(x)=x+1x(x0)

To draw the curve, substitute x=0.2 in the expression f(x)=x+1x.

f(0.2)=0.2+1(0.2)=5.2

Thus, the point is (0.2,5.2).

Substitute x=2 in the expression f(x)=x+1x.

f(2)=2+1(2)=2.05

Thus, the point is (2,2.05).

Substitute x=1 in the expression f(x)=x+1x.

f(1)=1+1(1)=2

Thus, the point is (1,2).

Substitute x=0.2 in the expression f(x)=x+1x.

f(0.2)=0.2+1(0.2)=5.2

Thus, the point is (0.2,5.2).

Substitute x=1 in the expression f(x)=x+1x.

f(1)=1+1(1)=2

Thus, the point is (1,2)
