range of e^{-x}-2

Solution

range

e^{- x} - 2

Solution

f (x) > - 2

+1

Interval Notation

(- 2, \infty)

Solution steps

The range of an exponential function of the form

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

is

f (x) > k

k = - 2

f (x) > - 2

Popular Examples

inverse of f(x)=(x^2)/9 inverse

f (x) = \frac{x ^{2}}{9}

range of y=-3tan(1/2 x)range

y = - 3 tan (\frac{1}{2} x)

domain of f(x)= x/(x^2+2x-3)domain

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

domain of sqrt(-(x-5)/2)domain

- \frac{x - 5}{2}

extreme f(x)=2x^3-24x^2+72x extreme points

f (x) = 2 x^{3} - 24 x^{2} + 72 x
