Chapter 1.3, Problem 28E

To determine

To find: zero of the function $f\left(x\right)=12$ and graph that function.

Answer to Problem 28E

None

  

Explanation of Solution

Given information:

The function is a follows:

  $f\left(x\right)=12$ … (1)

Calculation:

To find the zero of the function, put $f\left(x\right)=0$ in equation (1) and simplify it as follows:

  $\begin{array}{c}f\left(x\right)=12\\ 0\ne 12\end{array}$

Since $0\ne 12$ , this function cannot be zero. Therefore, this function does not have zero.

This function never crosses the x-axis because horizontal lines are parallel to the line $y=0$ . The graph for this function is as follows:
