Can someone help me with this math homework please!

1) (1,0) (2,0) and (-3,0)

2) F(x)>0 (-infinity,-4)

3) x goes to + infinity and the line goes to + infinity

4) 56

5) first choice

Step-by-step explanation:

1) see where the line touches the x-axis and no where else. There are 3 points where the line does touch them and those are the answers.

2) interval is usually the space of where you check. They said (-infinity,-4) so anything to the left of x= -4. Identify where the x-axis is and decide if the line is above or below it. Below= - Above= +

3) Line goes to top right. We need to understand that the right on the x-axis is positive and up on the y-axis is positive. so if it is going to the right and up, its going to (+infinity, +infinity)

4) Local maximum over interval. Like What I said for #2, its where you check. So check everything from x= -3 to x=1.5 and see the highest point as a y value. In this case, the highest or biggest number is 56.

5) Again intervals, You check the numbers and identify where the x-axis is and see if it is above or below

6/20

step-by-step explanation:

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
