Question

Identify which functions how complex roots by selecting the function names on the provided coordinate line select all the correct location on the image

Answer 1

Function a crosses the x-axis so it will have two real solutions.

Function b does not cross the x-axis so it will not have real solutions, but will have complex solutions.

Function c crosses the x-axis so it will have two real solutions.

Function d does not cross the x-axis so it will not have real solutions, but will have complex solutions.

Function e crosses the x-axis so it will have two real solutions.

Function f does not cross the x-axis so it will not have real solutions, but will have complex solutions.

Final Answer:

Functions b,d,f have complex solutions.
