Q. What is the inverse of the function g(x)=7x+3x5 g(x) = \frac{7x+3}{x-5} ? \newline g1(x)= g^{-1}(x) = \square
  1. Understand Inverse Function: Understand the concept of finding an inverse function. To find the inverse of a function, we need to swap the xx and yy variables and then solve for yy. This process will give us the inverse function, denoted as g1(x)g^{-1}(x).
  2. Original Function with y: Write the original function with yy instead of g(x)g(x).\newliney=7x+3x5y = \frac{7x + 3}{x - 5}
  3. Swap Variables: Swap the xx and yy variables to begin finding the inverse.x=7y+3y5x = \frac{7y + 3}{y - 5}
  4. Eliminate Fraction: Multiply both sides by (y5)(y - 5) to eliminate the fraction.x(y5)=7y+3x(y - 5) = 7y + 3
  5. Combine Terms: Distribute xx on the left side of the equation.\newlinexy5x=7y+3xy - 5x = 7y + 3
  6. Factor Out yy: Get all terms containing yy on one side and the constant terms on the other side.\newlinexy7y=5x+3xy - 7y = 5x + 3
  7. Solve for yy: Factor out yy from the left side of the equation.y(x7)=5x+3y(x - 7) = 5x + 3
  8. Solve for y: Factor out yy from the left side of the equation.\newliney(x7)=5x+3y(x - 7) = 5x + 3 Divide both sides by (x7)(x - 7) to solve for yy.\newliney=5x+3x7y = \frac{5x + 3}{x - 7}
