Answer:
The domain is (-∞,∞) and range is (k,∞)
Step-by-step explanation:
The graph is given as .
When x =0, we have f(x) = y intercept
Consider the exponential function y = .
This is defined for domain all real numbers and range = (0,infinity) for all positive a.
This function is transformed into our function by horizontal shift of h units to left and vertical units of k units up.
i.e. Y = y-k and X = x-h
Since x has domain as set of all real numbers X also set of real numbers
So domain is (-∞,∞)
Since range of original graph is (0,∞), we have Y minimum value as k and max as infinity.
Range = (k,∞)
