Finding Inverse and Log Properties

What is the inverse of the points (1,3)(2,4)(6,8)

• (3,1)(4,2)(8,6)
• (-3,-1)(-4,-2)(-8,-6)
• (1,3)(2,4)(6,8)
• (-1,-3)(-2,-4)(-6,-8)

Find the inverse 
f(x)=2x-2
     

• f^-1(x)=1/2x+1
• f^-1(x)=-2-1/2x
• f^-1(x)=-7/3x-20/3
• 2-2/5x

Find the inverse 
f(x)=-2x+8

• (8-x)/2
• 2/5x+2
• -x-4
• 1/3x+1/3

Find the inverse
