can someone please me with this
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.

Please i would really appreciate the help!!
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
so for the first question what would be the best fit
no do not use mine
make up your own and follow my example that way you will learn more and "see' how to apply
so how did u describe the direction of it
how do u find that
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.
and the direction of it opens up
is that correct?
can i plz have the complete answer
yes but use your own
you might want to use something with whole numbers too
I did not "check ahead" so the numbers here are not integers
can i have the answer for the example u provided
plz because this is my last question so i can complete my algebra 1 course these are my last questions can u just plz giv me the answer
you need to slow down and read the responses I even gave you the picture of the graph
for the example I used
for the example u used i just want to know what the direction of it is and the y intercepts and zeros
