match the function with its domain and range.
hold on im writing the equation
\[\sqrt[-]{5*x?}\]
i didnt mean to put the question mark there
here are the answer choices D: x < 0.75 & R: y > 3 D: x < 0 & R: y > 7 D: x> -2 & R: y> 0 D:x> 0 & R:y< 0 D: x >- 2 & R: y> 4 D: x> 0 & R: y> 0
@moha_10
You can see that the function is reflected in the x-axis, and begins from zero. You also know that you can't take the square root of any number, thus x as to be positive, leaving you with the fourth or sixth option. The square root of a positive number is always positive, put a negative in front, it will always be negative. Thus dom: x>0 and ran: y<0
YES sorry being late
lol ur fine and thanks @cherylim23 i knew the range was 0 but i was thinkin something else with the domain so thanks
oaky domain is from 0 to - infity and range is from 0 to infity
is that clear @janessia
yes it is! thanks!
coz the 5 multipier is just for scaling
Your best stab would be to plot the graph if you're unsure about the domain. Keep in mind you cannot take the square root of a negative number. Cheers
hmmm ohk
