## charlotteakina 3 years ago What is the domain of the following function? screenshot attached.

1. amorfide

domain is the set of x values you can put into the function so since it starts at -2 on the x axis and continues infinitely onwards domain: x>-2

2. amorfide

greater than or equal too -2

3. nustian

itc c option is correct because line contain -2 point on x axis also that is why ,also value is increassing furture from -2.

4. amorfide

to see if a quadratic has any solutions you will have to use the formula for the descriminant b²-4ac 3=a 5=b 10=c sub them in if x <0 no real solutions x=0 1solution x>0 2 solutions

5. amorfide

yes

6. amorfide

well it is less than zero you don't need the exact value you just need to know if it is negative, zero or positive

7. amorfide

lol as i stated before <0 is no real solutions =0 is 1 repeated solution >0 is 2 solutions

8. amorfide

well done :D any more questions?

9. amorfide

this is a horrible graph... i can not say for sure what the answer is, but I would say C, sorry about that

in any function whatever we put the value called domain and whatever it gives answer called range
