Use the graph of the function to find the domain and range o

Use the graph of the function to find the domain and range of f. domain range Use the graph to find the indicated function values. f(-2) = f(-1) = f(1/2) = f(1) =

Solution

Domain

There is no restriction on x value. Therefore domain i s (-infinity,infinity)

Range

From the graph we can say that the y values cant be less than -4

Therefore range is [-4,infinity)

a.f(-2)

when x=-2 y=0

therefore f(-2)=0
