f(x)= x+3 if -2<=x<1

9 if x=1

-x+2 if x>1

a. find the domain

b. locate the intercepts

I am totally lost, can someone please help me with this?

**Reiny**, Tuesday, March 26, 2013 at 10:10pmf(x0 = x+3 for -2 ≤ x < 1

f(x) = 9 , for x = 1

f(x) = -x+2 , for x > 1

strange graph.

I see a line segment from (-2,1) to (1,4) with a solid dot at (-2,1) (include the point) and an open dot at (1,4), exclude the point

The we have the isolated and lonely point (1,9) just sitting there all by itself.

then a ray starting at (1,1) (open dot, point not included)

with an x-intercept at (2,0) and dropping down into the fourth quadrant.

domain: x≥ -2

intercepts,

y-intercept at (0,3)

x-intercept at (2,0)
