Question

Please help n_n - this is a domain and range question trying to identify them in a graph.
(attachment included)

Answer 1

question with graph and answers are included in the attachment - i have no knowledge of this, i dont understand it ...

Answer 2

my interpretation would be that domain is (-infinity,infinity) and range is [-4,infinity) - what would the answer be ??

Answer 3

@hartnn would you mind helping me? n_n

Answer 4

domain is correct

Answer 5

for range, plug in end-points of domain as x values

Answer 6

like put x = -infinity and find f(x)
like put x = infinity and find f(x)

Answer 7

mmmhhhh ok

Answer 8

but where exactly ... there is no equation ... by any chance would the answer be
domain (-infinity,infinity) and range would be (k,infinity)

Answer 9

\(a^{-\infty } = 0 \)

\(a^{\infty } = \infty \)

Answer 10

in the equation
f(x) =a ^(x+h) + k

Answer 11

and yes,
then you will get the range as k,infinity

Answer 12

ohhh ok meaning the answer would be A n_n

Answer 13

correct! :)

Answer 14

yay i understood n_n thank you @hartnn

Answer 15

welcome ^_^
