Which function models exponential decay? Select all that apply. A f(x) = 150 (0.84)2+3 – 7
B f(x) = 150 (1 + 0.16)*-3 – 7
f (x) = 150 (1 – 0.16)2-3 + 7
D f(x) = 150 (1.16)2+3 +7

step-by-step explanation:

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
