Answer:
Step-by-step explanation:
Given is a graph
On observing the graph we find the following
The graph is increasing throughout its domain
Domain is the set of all real numbers.
Range is only (2,infty)
y is not defined for y <=2
Passes through (2,5)
No x intercept
y intercept is at one point between 2 and 3.
The graph looks like transformation of an exponential graph.
y = a^x+2 makes range and shape somewhat same.
When x=0, y=3 thus making y intercept also match.
Since passes through (2,5) we have
5 = a^2+2
Or a = sq rt 3
So graph is
y = 3^(x/2)+2
