Question

If `g(x) = 2x-5`, how do you find g(x)=1/3?

Answer 1

Possibility 1
You want to find the value of `x` for which `g(x) = 1/3` given `g(x) = 2x-5`
`color(white)("XXXX")` `2x-5 = 1/3`
`color(white)("XXXX")` `6x-15 = 1`
`color(white)("XXXX")`x = 16/6 = 8/3#

Possibility 2
You want to find the value of `g(x)` when `x=1/3`
`color(white)("XXXX")` `g(1/3) = 2(1/3)-5`
`color(white)("XXXX")` `color(white)("XXXX")` `= 2/3 -5`
`color(white)("XXXX")` `color(white)("XXXX")` `=- 4 1/3`
