Chapter 1.3, Problem 10CFU

To determine

To find: zero of the function $f\left(x\right)=19$ and graph that function. Write none if no zero exists.

Answer to Problem 10CFU

None

  

Explanation of Solution

Given information:

The function is a follows:

  $f\left(x\right)=19$ … (1)

Calculation:

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

  $\begin{array}{c}f\left(x\right)=19\\ 0=19\\ 0\ne 19\end{array}$

Therefore, $f\left(x\right)$ has no zero.

Compare the function with the slope intercept form $y=mx+b$ , to get

  $y=0,b=19$

Now, graph all the points including y-intercept, b, is at $\left(0,19\right)$ are located at $y=19$ .
