Answer:
a^2 - 2a.
Step-by-step explanation:
Replace the y in g(y) by a - 1 and simplify.
g(a-1) = (a - 1)^2 - 1
= a^2 - 2a + 1 - 1
= a^2 - 2a.
 
        
             
        
        
        
Answer:  y = 0x+3 or y = 3
The slope is 0 and the y intercept is 3. So m = 0 and b = 3. 
Plug those into y = mx+b to get y = 0x+3, and that simplifies to y = 3.
This graphs out a horizontal line that passes through the two points (0,3) and (1,3).
