Question

Determine whether each equation is a function.

$y=3x-5$

Short answer

When $x=2$, then $y=1$. Since each value of $x$, corresponds to only one value $y$the equation define a function

Step-by-step solution

Step 1. Given Information

We have

$y=3x-5$

Step 2. If x=2

$$\begin{gathered} y=3\left(2\right)-5 \\ y=1 \end{gathered}$$
