Describe the solution set of each of the following quadratic inequality or not

See below

All the inequalities can be solved by making a table, but once they are simple factored quadratic expressions, we already know what interval it will have.

Step-by-step explanation:

1)

Factoring the expression, we have

Considering that

for and you can see that for

Therefore,

2)

You can factor it again.

You can make the table to solve all the inequalities, but once we have the expression , we know that

, therefore,

3)

Factoring we have

Find the solutions for

And we know that

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
