Graphing Polynomial Functions Practice

1. A polynomial $p$ is graphed.

   
   

   What could be the equation of $p$?

   Choose 1 answer:

   1. $p(x)=x^2(2x-5)(x+2)$
   2. $p(x)=x(2x-5)(x+2)^2$
   3. $p(x)=x^2(2x-5)^2(x+2)$

   4. $p(x)=x(2x-5)^2(x+2)$

2. A polynomial $p$ is graphed.

   
   

   What could be the equation of $p$?

   Choose 1 answer:

   1. $p(x)=(x+3)(x+1)(2x-1)^2$
   2. $p(x)=(x+3)(x+1)^2(2x-1)$
   3. $p(x)=(x+3)^2(x+1)^2(2x-1)$

   4. $p(x)=(x+3)^2(x+1)(2x-1)$

3. A polynomial $p$ is graphed.

   
   

   What could be the equation of $p$?

   Choose 1 answer:

   1. $p(x)=2x^3(x-2)^2$
   2. $p(x)=2x^2(x-2)^3$
   3. $p(x)=2x^3(x-2)^3$

   4. $p(x)=2x^2(x-2)^2$

4. A polynomial $p$ is graphed.

   
   

   What could be the equation of $p$?

   Choose 1 answer:

   1. $p(x)=(x-1)(2x+7)^2(x+1)^2$
   2. $p(x)=(x-1)(2x+7)(x+1)^2$
   3. $p(x)=(x-1)^2(2x+7)^2(x+1)$
   4. $p(x)=(x-1)(2x+7)^2(x+1)$
