range of 3^{-x}

Solution

range

3^{- x}

Solution

f (x) > 0

+1

Interval Notation

(0, \infty)

Solution steps

The range of an exponential function of the form

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

is

f (x) > k

k = 0

f (x) > 0

Popular Examples

inverse of-5x+15 inverse

- 5 x + 15

domain of f(x)= 7/(1+e^x)domain

f (x) = \frac{7}{1 + e ^{x}}

domain of (2x)/(-9x^2+324)domain

\frac{2 x}{- 9 x ^{2} + 324}

f (x) = 7 x^{2} - 9 x - 5

line (-6,7),(2,-5)line

(- 6, 7), (2, - 5)
