1 Cumulative Review_A Name 1-9: Write an equation in the specified form from the given information 1.) Write a quadratic function with a vertex at (5, 11) and passes through the point (13, 27); in Vertex Form 3.) Write a linear function that goes through the points (-5, 6) and (10, 12); in Slope-Intercept Form 2.) Write a circle equation with center at (-3, 6) and a point on the circle (5, -10); in Center-Radius Form 4.) Write a cubic function that passes through at -4 and bounces at 6 and also goes through the point (5, 63); in Intercept Form 5.) Write an absolute value function using the table; in Vertex Form x f(x) ) Write a piecewise function using the graph 7.) Write a polynomial function using the graph; in Center-Radius Form in Intercept Form ) Write a circle equation from the graph; 9.) Write a quadratic function from the graph; in General Form in Standard Form
