1) The x-intercept of the function y=f(x) is 5, so the x-intercept of y=f(x)^2 is also 5. 2) The coordinates of the point on the graph of y=g(x) are (-3,5), so the coordinates of the point on the graph of y=g(-x) are (3,5). 3) To write the equation of a function f(x) that is shifted down 4 units and compressed vertically by a factor of 2, the equation would be y = 1/2f(x) - 4.
