range of f(x)=4^{x-2}

range

f (x) = 4^{x - 2}

f (x) > 0

Interval Notation

(0, \infty)

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

in v erse f (x) = 2 - 2 x + 1

d o main f (x) = \frac{x}{x ^{2} - 36}

in v erse f (x) = \frac{3}{4} x + 9

in v erse f (x) = ln (3^{x}) - 2

in v erse f (x) = 8 x^{2}
