Best ResponseYou've already chosen the best response.1Find the vortex of the equation as you can tell it is a parabola, then restrict the domain so it can pass the horizontal line test The horizontal line test dictates that a line drawn across a graph should not intersect the line more than once. For a function to have an inverse it must pass this test

Best ResponseYou've already chosen the best response.4\[f(x)=x^26x+9=(x3)^2.\]Obviously, \(f:[3,\infty)\to\mathbb{R}\) or \(f:(\infty,3]\to\mathbb{R}\).
