Question

Using the equation y = 3x – 5, what would the output be for an input of -4?A) -7B) .3C) -17D) -3

Answer 1

Given the equation:

$y=3x-5$

Where x represents the input value, and y is the output value. For an input of -4 (x = -4), we use the equation to find the corresponding output:

$\begin{gathered} y=3(-4)-5=-12-5 \\ \\ \therefore y=-17 \end{gathered}$

Answer: C
