Find the values of x for which f(x)=g(x). f(x)=x^2, g(x)=x+2

Which approach to the theory-and-research cycle does the following sequence reflect: (1) specific observations suggest generalizations, (2) generalizations produce a tentative theory, (3) the theory is tested through the formation of hypotheses, and (4) hypotheses may provide suggestions for additional observations?

Me with this one question, and i'll upvote the brainliest answer

What is the value of f(x) = 2.2 for f(-2)?
