range of f(x)=3(2)^x-4

range

f (x) = 3 (2)^{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

f (x) = 6 x^{4} - 36 x^{2}

2 x - y = - 3

y = - x + 4

f (x) = x^{2} + 2 x - 3, x \leq - 1

(- 3, 5), (7, - 9)
