What is x for x^2+2 and y=-3
1 answer:
Hello there! Below this is an attachment of my work for this question and how to solve for it. Allow me to convert my explanation here.
What we are dealing with is called "Composition of Functions", or at least I call it that.
Primarily, we are given the function "g(x)", which just means "G of x".
Whenever we have a problem that states "Find G(#)", we are replacing every single "x" with the number in the given function.
For example;
f(x) = 4x + 2, find f(2)
Replace "x" with 2.
f(2) = 4(2) + 2
f(2) = 8 + 2
f(2) = 10 is your answer.
Hopefully, we now understand our concept of solving this problem.
Take a look into my answer below on paper. Please advise me of any miscalculations or misunderstandings you may find, and I will try my best to elucidate my answer.
I hope this helps!
