Relation given:-

  • {(-2,5),(-1,3),(0,-1),(1,-3),(2,-5),(3,-7)}

Inverse

  • {(5,-2),(3,-1),(-1,0),(-3,1),(-5,2),(-7,3)}

#2

  • f(x)=2x-3

Let it be y

[tex]\\ \tt\hookrightarrow y=2x-3[/tex]

[tex]\\ \tt\hookrightarrow 2x=y+3[/tex]

[tex]\\ \tt\hookrightarrow x=y+3/2[/tex]

Write in terms of x

[tex]\\ \tt\hookrightarrow f^{-1}(x)=\dfrac{x+3}{2}[/tex]
