a) f(t) = 250(1.05t) b) f(t) = 175(0.97t) c) f(x) = 20(1.10)x d) f(x) = 320(0.98)x

Respuesta :

A) growth; B) decay; C) growth; D) decay

A is growth because the value of b raised to the exponent is larger than 1.
B is decay because the value of b raised to the exponent is smaller than 1.
C is growth because the value of b raised to the exponent is larger than 1.
D is decay because the value of b raised to the exponent is smaller than 1.
