• It is even

• It is odd

• It is a binomial

• None of the above

If it is given that g is an even polynomial. Which statement below is true ?

• g(-x)=g(x)

• g(-x)=-g(x)

• g has a domain of $\left(0,\infty\right)$

• None of the above

Is the following graph continuous ?

• yes

• no

• Can't tell

Is the following graph continuous ?

• Yes

• No

• Can't tell

 Compute $\lim_{x\rightarrow\infty}f$ for this graph (Hint : what is the end behavior of y as the x values become very big)

• 0

•  $-\infty$  

• + $\infty$  

• All of the above

Given that f is a polynomial has the following xy table. On which intervals do you think there is a root ? (Hint : the sign of y should shift so that the graph crosses the x axis)

• x between -2 and 1

• x between -1 and 0

• x between 0 and 1

• There is no root

If for a>b, f(a)>f(b) then f is

• continuous

• decreasing

• increasing

• constant

The following graph is

• decreasing

• increasing

• even

• None of the above
