the graph of y = f(x) is the solid black graph below. which function represents the dotted graph?
the graph of y = f(x) is the solid black graph below. which function represents the dotted graph?
Answer
Explanation:
Step1: Identify transformation
The dotted - graph is a vertical shift of the solid - graph (y = f(x)) downwards. If the original function is (y = f(x)) and the vertical shift is (k) units downwards, the new function is (y=f(x)-k).
Step2: Determine the shift amount
By observing the graph, the solid - graph (y = f(x)) is shifted down 9 units to get the dotted graph. So the function of the dotted graph is (y = f(x)-9).
Answer:
(y = f(x)-9)
