To move the graph up or down, use the transformation f(x) + k. Write the function thathas the same vertical translation as your project. HINT: Use the y-coordinate of thevertex to identify the vertical shift.3.a(x^2)+20To move the graph to the right or left, use the transformation f(xh). Change thefunction you wrote in part 4b to have the same horizontal translation as your project.HINT: Use the x-coordinate of the vertex to identify the horizontal shift.(x-30)^25. Complete your function by solving for a. To do this, substitute the coordinates of one ofthe endpoints that you identified in part 2b into your transformed function.What is a? (2 points)
Use this value of ato write the function that represents your structure. (1 point)
Rewrite your function in standard form. HINT: First square the binomial, then multiply each termby the constant, a. Round the coefficients and constant to 2 decimal places. (2 points)
Confirm your function:
6. Use the Graphing Tool to graph your function. First click the parabola symbol, and thentwo points on the graph. For a parabola that opens upward, first select the vertex and thenthe right endpoint. For a downward opening parabola, select the vertex and then the leftendpoint.When you are satisfied that the graph matches your sketch, write down the functiondisplayed on the graphing tool. (2 points)7. Compare your function to the Graphing Tool function. Are the signs the same? Are thecoefficients reasonably close? (1 point)
