Answer :
Having the expression for f(x), and knowing the value of f(x) (-22), we just need to equate those expressions:
[tex]f(x)=5x-2=-22[/tex]Obtaining the following equation with one unknown:
[tex]5x-2=-22[/tex]Solving for x:
[tex]\begin{gathered} 5x=-22+2 \\ \\ 5x=-20 \\ \\ x=-\frac{20}{5} \\ \\ x=-4 \end{gathered}[/tex]Answer B: when f(x) = -22, we have that x = -4.
And this will correspond to the point (-4,- 22)
