range of f(x)=2*3^{x-1}-4

range

f (x) = 2 \cdot 3^{x - 1} - 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

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

f (x) = \frac{12 x}{8 x ^{2} + 1}

f (x) = x + 2 - 25 - 5 x

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

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

What is the range of f(x)=2*3^{x-1}-4 ?
