Question

Find each value if $f\left(x\right)=3x-5$ and $g\left(x\right)=x^2-x$. 

$f\left(a\right)$

Step-by-Step Solution

Answer

The value of $f\left(a\right)$ is $3a-5$.

Step 1 – Select the correct function.

_{The given functions are:}

_{$\begin{array}{l}f\left(x\right)=3x-5\\ g\left(x\right)=x^2-x\end{array}$}

_{The required function for the value} $f\left(a\right)$is$f\left(x\right)=3x-5$.

Step 2 – Substitute the value in the selected function.

Substitute $x=a$in the function $f\left(x\right)$.

$f\left(a\right)=3\left(a\right)-5$

Step 3 – Calculate the value by simplification.

$\begin{array}{l}f\left(a\right)=3\left(a\right)-5\\ f\left(a\right)=3a-5\end{array}$

Thus, the value of $f\left(a\right)$ is $3a-5$.
