range

f (x) = - 4^{x}

Solution

f (x) < 0

+1

Interval Notation

(- \infty, 0)

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

range of \sqrt[3]{x-8}range

asymptotes of f(x)= 1/(x-3)+2 asymptotes

f (x) = \frac{1}{x - 3} + 2

range of f(x)=x^2-25,x>= 5 range

f (x) = x^{2} - 25, x \geq 5

domain of (x-8)^2 domain

(x - 8)^{2}

inverse of f(x)= 1/(x+1)inverse

f (x) = \frac{1}{x + 1}
