Question

Consider
f(x) = cos 5x
g(x) = −4 + cos 5x
Which statement best describes the relationship between the graphs of f and g?

Answer 1

1. The graph of g has 4 times the amplitude
of the graph of f.

Answer 2

2. The graph of g is a vertical shift upward
by 4 units of the graph of f

Answer 3

4. The graph of g has one-half the amplitude
of the graph of f.

Answer 4

5. The graph of g is a vertical shift downward
by 4 units of the graph of f.

Answer 5

It is #5

Answer 6

shld I explain?

Answer 7

yes please.

Answer 8

we can rewrite g(x)=cos(5x)-4

Answer 9

Did you learn how to tell the changes in a graph

Answer 10

i forgot what that is called exactly

Answer 11

oh its called transformations

Answer 12

y=a(x-k)+b
The b shifts the graph vertically up or down
since it is negative it shifts th egraph down if it would be positive it wld shift th egraph upwards
