3 of 11 3 OK SolutionDomain graph extends beyond the values

Solution

Domain: graph extends beyond the values shown in graph

So, ( - inf , inf)

Range: y values that exist for the graph .

min y = 1 and max y --> infinity

[ 1 , infinity

X intercept : graph does not cut x axis.So, x intercept

Y intercept : graph cuts the y axis at ( 4, 0)

f(2) : At x = 2; y = 2 from the graph

So, f(2) = 2

f(4) : At x = 4 ; y = 2 from the graph

So, f(4) = 2
