Needed with explanation

Ateacher noticed 5/8 of the students were wearing either blue shorts or white shorts. write two different ways this could be done.

What are the domain and range of the function f(x)=2^x+1

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
