• True

• False

In the function f(x) graphed in the picture, what is f(1)?

• 
  

  $\frac{1}{2}$

• -2

• 1

• undefined

The graph of f(x) is given in the picture. For this function f(-1) = f(2)

• True

• False

What is the domain of f(x) shown in the graph?

• $\left\{x\left|x\in R\right|\right\}$

  $\left(-\infty,\infty\right)$
  
  domain is all real numbers

• $\left(-\infty,3\right)\cup\left(3,\infty\right)$ $\left\{x\left|\ x\in R,\ x\ne3\right|\right\}$

  
  domain is all real numbers except x is not equal to 3.

• $\left[-2,3\right)\cup\left(3,5\right]$ $\left\{x\left|-2\le x\le5,\ x\ne3\right|\right\}$

  
  domain is all real numbers from x=-2 to x=5 except x cannot equal 3
  

• $\left[-2,5\right]$ $\left\{x\left|-2\le x\le5\right|\right\}$ \
  domain is all real numbers from -2 to 5

The range for f(x) shown in the graph is all real numbers

 $\left(-\infty,\infty\right)\ \ \left\{y\left|\left\{y\in R\right\}\right|\right\}$  

• True

• False
