### Question:

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

### Answer:

(a) f(1)= 3

(b) when x=-1 , y is about -0.3, f(-1)=-0.3

(C) x=0,3

(d) x=-0.7

(e) The domain of consists of all x-values on the graph of f . For this function, the domain is [-2,4]. The range of consists of all y-values on the graph of f . For this function the range is [-1,3]

(f) at interval [-2,1]
