Answer 16

Write an exponential function y = ab^x for a graph that includes (1, 15) and (0, 6).
= 3(5)x
y = 2.5(6)x
y = 6(2.5)x
y = 5(3)x

Answer 17

are the x's supposed to be ^x's??

Answer 18

if so, its C

Answer 19

how is the graph of y=-1/2 (5)^x-3 translated from the graph y=1/2 (5)^x
reflected across the y-axis and 3 units down
reflected across the x-axis and 3 units down
reflected across the x-axis and 3 units left
reflected across the y-axis and 3 units right

Answer 20

ok based on the graph that i made, the answer would be

Answer 21

B. reflected across the x-axis and 3 units down

Answer 22

hell yeah i passed the test!!
