Question

I need help with this problem. Answer in interval notation please.

Answer 1

Given:

a graph of the function y = x^2 is given.

Find:

we have to find its domain and range.

Step-by-step explanation:

Since x can be any real number, so the domain of the function y=f(x)=x^2 is Set of Real Number(R) i.e.

`(-\infty,\infty)`

And, since y is always positive for any real value of x, so range of y = f(x) = x^2 is positive Real Number, i.e.

`[0,\infty)`

Conclusion:

Therefore, Domain of the given graph is (-infinity,infinity) and range is [0,infinity).
