can someone please me with this Part B The second part of the new coaster is a parabola. Ray needs help creating the second part of the coaster. Create a unique parabola in the pattern f(x) = ax2 + bx + c. Describe the direction of the parabola and determine the y-intercept and zeros. The safety inspector notes that Ray also needs to plan for a vertical ladder through the center of the coaster's parabolic shape for access to the coaster to perform safety repairs. Find the vertex and the equation for the axis of symmetry of the parabola, showing your work, so Ray can include it in his coaster plan. Create a graph of the polynomial function you created in Question 4.

    in general when a is positive the parabola opens up and when a is negative the parabola opens down. the y-intercept the values of x when y = 0 the vertex is the maximum or minimum value of y when the value of x is the line of symmetry. vertex form for the equation of a parabola a(x-h)^2 + k where h = -b/2a the x-value and k is the corresponding y-value

    this is just general information for any parabola remember I don't have your specific equation so I cannot verify.

    Create a unique parabola in the pattern f(x) = ax2 + bx + c. you should make one up

    here my a is 2 positive graph open up when y = 0 solve for x = -3.69 and 0.69 total distance = around 4 1/2 of that around 2 so line of symmetry and x-value for vertex -3.69 + distance to line = -1.5 f(-1.5) = minimum = -9.5 vertex (-1.5, -9.5)

    so the direction is that it opens up right?

    if a is positive the parabola opens up if a is negative the parabola opens down

    so for the first question a parabola would be 2x^2 + 6x - 5.
