Question

Consider the functions f(x) = and g(x) = + 6. What are the ranges of the two functions?

f(x): y

g(x): y

Answer 1

it is 0 6

Explanation:

Answer 2

the correct question in the attached figure

we have that

f(x) = (4/5)^x
g(x) = (4/5)^x + 6

using a graph tool
see the attached figure

we know that
f(x) has the horizontal asymptote y = 0
g(x) has the horizontal asymptote y = 6

therefore
the range of f(x) is the interval (0,∞)
the range of g(x) is the interval (6,∞)

the answer is
the range of f(x) is the interval (0,∞)
the range of g(x) is the interval (6,∞)
