G12BAA ST1.1 Analyzing Graphical Representations of a Function

Determine whether the function is even, odd or neither.    $f\left(x\right)=4x^4-2x+2$  

 

• even

• odd

• neither

• not a function

Use the graph to find the domain.

• $\left[-4,\ 4\right)$

• $\left(-4,\ 4\right)$

• $\left[-1,\ 6\right]$

• $\left(-4,\ 4\right]$

Use the graph to find the range.

•  $\left[-1,\ 6\right]$ 

•  $\left(2,\ 3\right]$ 

•  $\left(-1,\ 4\right)$ 

• $\left(-4,\ 4\right]$

Find the y-intercept.

• $6$

• $5$

• $2$

• $-6$

Find the zero(s) of the function.

•  $5\ and\ 6$ 

•  $-3\ and\ -2$  

•  $-2\ and\ -1$ 

•  $6$ 

Use the graph to test for symmetry.

• symmetric with respect to x-axis

• symmetric with respect to y-axis

• symmetric with respect to origin

• symmetric with respect to x-axis, y-axis and origin

Find the domain.   $f\left(x\right)=\frac{8x+12}{x^2+5x+4}$   

•  $\left\{x\left|\ x\ne-4,\ \ x\ne-1,\ x\in R\right|\right\}$  

•  $\left\{x\left|\ x\ne-2,\ \ x\ne-3,\ x\in R\right|\right\}$  

•  $\left\{x\left|\ x\ne-5,\ \ x\ne-1,\ x\in R\right|\right\}$  

•  $\left\{x\left|\ x\ne5,\ \ x\ne1,\ x\in R\right|\right\}$
