What’s the awnser for this???

If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=

Need match the functions with correct transformation. f(x) = -3x f(x) = |x-1|+3 f(x) = √(x+3) 1/2x² f(x) = (x+1)²-3 4|x| 1. compress by a factor of 1/2 2. stretch by a factor of 4 3. shift to the left 3 4. shift to the left 1 5. shift up 3 6. reflection

Use a transformation to solve the equation. w/4 = 8 can you also leave a detailed explanation on how this equation = 32
