Help...
#3 the answer is correct, but leave it as a square root.
#4 you have one set of numbers listed, but you did not identify them as a domain or range. There should be two sets of numbers listed.
#10 double check the exponent for y
#11 & 15 where are these questions? ALL level 2 and 3 questions have to be answered before I can give you a grade.
#13 What kind of function is this?
#14 shifted to the left how many units?

TheMind is saying this
\[\Large 10\sqrt{3}+2\sqrt{3} = 12\sqrt{3}\]

i see what went wrong, y^2 divided by y^-5 is
y^(2-(-5)) = y^(2+5) = y^7
So (y^7)^3 = y^(7*3) = y^(21)

# 11
what did you get? yes or no
-------------------------------
# 12
It's not a function since it fails the vertical line test (a vertical line can be drawn where it passes through more than one point)
-------------------------------
# 13
Correct

# 13
the parent function is \(\Large f(x) = x^2\)

for #14, the parent function is \(\Large f(x) = \sqrt{x}\)

#14 shifted to the left how many units?

2 because the endpoint of \(\Large f(x) = \sqrt{x}\) is at (0,0)

@jim_thompson5910 #14. What you've told me about the parent function is true, but now you need to tell me how the function in the question has been moved, compared to the parent function

you already said it: shift the parent function 2 units to the left
