Question

please help

Which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x) + 20? (3 points)

The graph of y = f(x) will shift left 20 units.
The graph of y = f(x) will shift down 20 units.
The graph of y = f(x) will shift up 20 units.
The graph of y = f(x) will shift right 20 units.

Answer 1

if we are shifting left or right, we would have () around the equation

Answer 2

for (x+5) shift left 5 units. (x-5) shift right 5 units. Since there is no () those choices can be eliminated

Answer 3

which ones are eliminated?

Answer 4

"if we are shifting left or right, we would have () around the equation" your equation doesn't have parenthesis around it

Answer 5

so the ones that say "will shift left" or "will shift right" I eliminate?

Answer 6

yesl.... all we have to do is pay attention to the sign.

Answer 7

ok... is it, "The graph of y = f(x) will shift up 20 units."?

Answer 8

^___^ yeah!

Answer 9

could you help me with a couple more problems?
