Answer:
i think the answer is c.) which is square root
Step-by-step explanation:
Answer:
C. Square root.
Step-by-step explanation:
We have been given 4 choices. We are asked to determine, which of the given functions has a domain of x ≥ 0.
A. linear.
We know that linear function is in form [tex]y=mx+b[/tex], which is defined for all values of x, therefore, option A is not a correct choice.
B. Square
We know that a square function is in form [tex]y=x^2[/tex], which is defined for all values of x, therefore, option B is not a correct choice.
C. Square root.
We know that a square root function is in form [tex]y=\sqrt{x}[/tex]. We also know that a square root function is not defined for negative values of x, so a square root function is defined for all values of [tex]x\geq 0[/tex]. Therefore, option C is the correct choice.
D. Cube
We know that a cube function is in form [tex]y=x^3[/tex], which is defined for all values of x, therefore, option D is not a correct choice.
