Expert Answer

Step 1

We’ll answer the first question since the exact one wasn’t specified. Please submit a new question specifying the one you’d like answered.

y=x^2+6x+5

This is equation has degree 2 and lead coefficient = 1 (positive). So both sides of this function will go upwards. 

That is , when x approaches +infinity or -infinity then y approaches +infinity.

Step 2

 We set y=0 to find the x intercepts. 

That gives: x=-5 and x=-1

So x intercepts are (-5,0) and (-1,0).
