CCSS.HSF.IF.A.1

Determine the values of the range:

 $\left(9,-2\right),\left(4,\ 3\right),\left(8,\ 10\right),\left(-4,\ 8\right)$ 

•  $\left\{-4,\ 4,\ 8,\ 9\right\}$ 

•  $\left\{-2,\ 3,\ 8,\ 10\right\}$ 

•  $\left(9,-2\right),\left(4,\ 3\right)$ 

•  $\left(8,\ 10\right),\left(-4,\ 8\right)$ 

Given: $y=2x^4+3$  

Determine the variable that represents the input.

CCSS.HSF.IF.A.1

Determine the domain and range for the given function:

 $\left\{\left(0,\ 1\right),\left(1,-3\right),\left(2,-4\right),\left(-4,\ 1\right)\right\}$ 

• Domain:  $\left\{1,-3,-4\right\}$  
  Range:  $\left\{0,\ 1,\ 2,-4\right\}$  

• Domain:  $\left\{0,\ 1,\ 2,-4\right\}$ 
  Range:  $\left\{1,-3,-4\right\}$ 

• Domain:  $\left\{0,\ 1,\ 2,\ 3,\ 4\right\}$ 
  Range:  $\left\{1,-3,-4\right\}$ 

Determine if the relation is a function and explain your answer.

• Yes, because the x-value 11 has two y-values paired 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 paired with it.

• No, because each x-value has only one y-value paired with it.
