11 A y2x B y22x53 12 A y25x B y25x24 13 A y5x BY5x Describe

11) A: y=2^x B: y=2^2x+5-3

12) A: y=2(.5)^x B: y=2(.5)^x-2+4

13) A: y=5^x B:Y=-5^x

Describe the change from function A to function B

Solution

11) graph is compressed by .5 and shifted 2.5 along x axis towards -x and shifted 3 units downwards

12) graph is shifted 2 units towards right along x axis and 4 units upwards

13) graph is mirror image of A in x axis
