Question

I'm getting a little confused as to when and where the values exist and don't. Thank you in advance for helping me to solve this!

The graph of a function f is given State the value of f(1). Estimate the value of f(-1). For what values of x is f(x) = 1? (Enter your answers as a comma-separated list.) x = Estimate the value of x such that f(x) = 0. x = State the domain and range of f. (Enter your answer using interval notation.) domain range On what interval is f increasing? (Enter your answer using interval notation.)

Explanation / Answer

a)f(1)=3

b)f(-1)=-1/4

c)f(x)=1 for x=1

d)f(x)=0 for x=-3/4

e)domain: [-2,4]

range:[-1,3]

f)increasing in [-2,1]
