Question

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

Answer 1

x=1 y= 7

x=2 y= 10

x=3 y= 13

Explanation:

y=3x+4

y=3(1)+4

=7

y=3(2)+4

=-10

y=3(3)+4

=13

Answer 2

For this case we have the following equation:

`y = 3x + 4`

We must find the value of the variable y when the variable x takes certain values.

For
`x = 1:`

`y = 3 (1) +4\\y = 3 + 4\\y = 7`

For
`x = 2:`

`y = 3 (2) +4\\y = 6 + 4\\y = 10`

For
`x = 3:`

`y = 3 (3) +4\\y = 9 + 4\\y = 13`

Thus, the values of y are 7,10,13 respectively.

Answer:

`y = 7\\y = 10\\y = 13`
