22. State the domain of the function y=3x+2
a. D: Real numbers
b. D: x not equal to 0
c. D: x < 0
A?
23. State the range of the function y=2x^2
a. R: y greater than or equal to 0
b. R: x not equal to 0
c. R: y < 0
I'm not sure?
24. Is y=sqrt2x a function?
a. Sometimes
b. Yes
c. No
B?
25. Is y=3x^2-2 a function?
a. No
b. Yes
c. Sometimes
A?
43. State the domain of the function y=3/x
a. D: x not equal to 0
b. D: x < 0
c. D: all real numbers
A?
Thanks
23. y ≥ 0
25 y = 3x^2 - 2 is definitely a function
