Chapter 8.1, Problem 8CYU

To determine

To calculate: Find the value of function $f\left(-9\right)$ .

Answer to Problem 8CYU

The value of the function $f\left(-9\right)$ is $-58$ .

Explanation of Solution

Given that: Function $f\left(x\right)=6x-4$ , where $x$ is variable.

Calculation:

At the different value of $x$ we get the different value of the function.

Therefore, at $x=-9$ , the value of the function $f\left(x\right)$

  $\Rightarrow f\left(-9\right)=6\left(-9\right)-4$

  $\begin{array}{l}\Rightarrow f\left(-9\right)=6\times \left(-9\right)-4\\ \Rightarrow f\left(-9\right)=-54-4\\ \Rightarrow f\left(-9\right)=-58\end{array}$
