Question

Given a function described as equation y = 3x + 4, what is y when x is 1, 2, and 3?

Answer 1

Consider the equation $y=3x+4$

Require to find $y$ when $x=1,2,3$

Now $x=1\Rightarrow y=3(1)+4=7$

$x=2\Rightarrow y=3(2)+4=10$

$x=3\Rightarrow y=3(3)+4=13$

Therefore, the values of $y$ are: $y=7,10,13$
