Answer: [tex]x\geq 0[/tex] Option A is correct
Explanation:
domain is the value of x in a given interval. In the given graph we can see that function lies from 0 to infinite.
Hence, x can take all values from [tex][0,\infty )[/tex]
Option B is incorrect because graph is not varying in the interval [tex]-9\leq x \leq 5[/tex]
Option C is incorrect because real number contains all numbers from negative axis to positive whereas this graph only lies in positive x-axis
Option D is Incorrect because y is extended after 10 also so it is not lying in the interval [tex]0\leq x\leq 10[/tex]
