Respuesta :
The value of [tex]f(x) = 9x[/tex] when [tex]x = -2[/tex] will be [tex]-18[/tex] .
What is function of [tex]x[/tex] i.e. [tex]f(x)[/tex] ?
A function is defined as a relation between a set of inputs having one output each.
We have,
[tex]f(x) = 9x[/tex] and [tex]x = -2[/tex],
So,
To find [tex]f(x)[/tex], substitute [tex]x = -2[/tex],
[tex]f(-2)=9*(-2)[/tex]
[tex]f(-2)=-18[/tex]
i.e.
[tex]f(x)=-18[/tex]
Hence, we can say that the value of [tex]f(x) = 9x[/tex] when [tex]x = -2[/tex] will be [tex]-18[/tex] .
