Answer:
a) y = x+1
b) The transformation shifts the graph 1 unit to the left
Step-by-step explanation:
a) Put (x+1) where (x) is in the function definition:
y = f(x+1)
y = x+1
__
b) This transformation has the effect of shifting the graph one unit to the left. Any point (x, f(x)) on the original curve, will now be (x-1, f(x)), shifted one unit to the left.
