i need help with questions 1-5 please help!

1. Put each parabola into vertex form. a. y= x2 +6x -3 b. f(x) = 4x2 -x-3 c. g(x) = -2x2 - 8x +9 d. H(x) = 2x2 +6x -12 2. Make the graph of each without using a calculator. List the domain, range and describe the end behavior. a. f(x) = 2(x-3)2 -4 b. T(x) = #x2+2x+3 c. j(x) =-x2 +4x 3. Find the value of a so that the function is continuous. a. H(x) = 5 - x x5 3 x + a x> 3 b. A (x ) = xsa 2 - x x > a 4. Using your calculator, make a representative graph of each function. List the domain, range, and describe the end behavior. What patterns do you notice? a. y = x' b. f(x) = x3 -9x c. m(x) =-x3+2x2 +5x-6 d. y =x* e. p(x) = -x5 f. g(x) = x5 - 4x3 5. Hope is reading about economic models. She reads the formula for one predictor uses x15. What can you tell her about the end behavior of this model? Why do you think this
