Functions and Equations Practice

The video tutorial explores functions, their relation to coordinates, and solving equations by working backwards. It begins with evaluating h(x) = 2x for values between 0 and 3, finding corresponding coordinates. Next, it demonstrates solving f(x) = 3x + 1 for C when f(C) = 31, using algebraic manipulation. Finally, it covers solving G(x) = 2x^2 + 2 for B when G(B) = 34, highlighting the importance of considering both positive and negative roots.
