range of f(x)=15(1/3)^x

range

f (x) = 15 (\frac{1}{3})^{x}

f (x) > 0

Solution steps

The range of an exponential function of the form

c \cdot n^{a x + b} + k

f (x) > k

k = 0

f (x) > 0

f (x) = \frac{( 3 x - 5 )}{( 2 x + 7 )}

f (x) = - 6 x - 7

f (x) = 2.8 + 4.2 x - 1.6 x^{2}

f (x) = \frac{4 x + 9}{3 x - 6}

(\frac{π}{6}, 6), (\frac{π}{4}, 0)
