Question

Starting with the graph of f(x)=7x, write the equation of the graph that results from 

(a) shifting f(x) 1 units downward.  y=    

(b) shifting f(x) 8 units to the left.  y=    

(c) reflecting f(x) about the y-axis.  

Answer 1

Some rules:

shift down, y=f(x)-offset

shift left, y=f(x+offset)

reflect about y-axis, y=f(-x)
