cal 2 Suppose the graph of f is given Describe how the graph

Suppose the graph of f is given. Describe how the graph of each function can be obtained from the graph of f. y = -f(x) + 2 y = 9f(x) - 2

Solution

a)

It is the second one: reflect about the x-axis, then shift up 2 units

b)

it is the second one too: Shrink vertically by a factor of 9, then shift down 2 units
