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

range

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

f (x) > - 4

Interval Notation

(- 4, \infty)

Solution steps

The range of an exponential function of the form

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

f (x) > k

k = - 4

f (x) > - 4

(- 3, - 1), (2, 0)

x + x + 8

f (x) = \frac{2 x - 5}{x ( x - 3 )}

y - 2 = 3 (x - 1)

f (x) = \frac{3 x + 7}{2 x + 1}
