In summary, pre-calculus is a branch of mathematics that serves as a foundation for calculus and other higher-level math courses. It covers topics such as functions, graphs, polynomial and rational functions, exponential and logarithmic functions, trigonometric functions, and vectors. It is different from algebra in that it introduces new concepts and involves more complex problem solving. Pre-calculus has various applications in fields such as engineering, physics, economics, and computer science. To prepare for pre-calculus, it is important to have a strong foundation in algebra, geometry, and trigonometry. Practice problems and review concepts from these courses to ensure a smooth transition into pre-calculus.

F(X) = x^2 + 2; G(X) = x - 3

F times G

Now, I don't know if this problem is different but for the times sign for F times G, its an open circle, its not solid.

Answer is (x - 3)^2 + 2 or x^2 - 6x + 11

Given [tex]f(x) = x^2 + 2[/tex] and [tex]g(x) = x-3[/tex] Find [tex]fg(x)[/tex] which is not quite the same as f(x)*g(x). You're supposed to find the composite function fg(x). I don't see the problem.

FoG(x) is defined as F(G(x)).

Since F(X) = x^2 + 2 and G(X) = x - 3,
F(G(x))= F(x-3)= (x-3)^2+ 2.
