If a parent function is y=2x which is the function of the graph

if the line is on the positive side then your answer is "y=2^x+1 +2"

if the line is on the negative side your answer is "y=2^x-1 +2"

Positive  always goes with positive

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
