Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

 $f\left(x\right)\ =\ 3x^2\ +\ x\ -\ 5$  

Given the function above, evaluate  $f\left(\frac{1}{2}\right)$  .

 $h\left(x\right)\ =\ \frac{1}{x^2\ -\ x}$  

Evaluate the function when x = 1:

 $h\left(x\right)\ =\ \frac{1}{x^2\ -\ x}$  

Evaluate the function when x = -6:
