Solution

range

y = 2^{- x} + 1

Solution

f (x) > 1

+1

Interval Notation

(1, \infty)

Solution steps

The range of an exponential function of the form

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

is

f (x) > k

k = 1

f (x) > 1

Popular Examples

domain of (x^2-1)/(4x+16)domain

\frac{x ^{2} - 1}{4 x + 16}

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

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

inverse of f(x)= 1/(4pi^2)x(4pi-x)inverse

f (x) = \frac{1}{4 π ^{2}} x (4 π - x)

distance (0,0),(1,2)distance

(0, 0), (1, 2)

asymptotes of f(x)=(1-x^2)/x asymptotes

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