Question

For $f\left(x\right)=2x–3$ finding each value.

$f\left(1\right)$

Short answer

The value$f\left(1\right)$ is –1.

Step-by-step solution

Step 1. From question.

The given expression is$f\left(x\right)=2x-3$

Step 2. To find.

Find the value of $f\left(1\right)$for$f\left(x\right)=2x-3$

Step 3. Evaluation.

Putting $x=1$ in $f\left(x\right)=2x-3$, we get

$\begin{array}{c}f\left(1\right)=\left(2\cdot 1\right)-3\\ =2-3\\ =-1\end{array}$

Hence, the value of $f\left(1\right)$for $f\left(x\right)=2x-3$is –1.
