Create a quadratic model equation in vertex form with these transformations. It must shift to the left a least 5 units and move up. The parabola must have a vertical compression. After your model is formed, calculate the y-value when x is 4 and sketch your model by hand on an organized graph on paper to be submitted.​

Lin is writing an equation to model the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded. she knows that the total cost to download 3 videos was $12. her work to find the equation is shown below. joylin’s work step 1 k= 3/12= 0.25 step 2 y= 0.25x where did joylin make her first error?
