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

so for the first question what would be the best fit

i dont think im onthe graphing part yet

im still on the create a unique parabola part

this is just general information for any parabola remember I don't have your specific equation so I cannot verify.
triciaal
  • triciaal
take your time and incorporate the info I provided let me know when you need more help
anonymous
  • anonymous
can i just get an example of a parabola with that equation
triciaal
  • triciaal
read your question that is the equation for a parabola

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

thats the thing

thx

no do not use mine make up your own and follow my example that way you will learn more and "see' how to apply
anonymous
  • anonymous
ok
anonymous
  • anonymous
so how did u describe the direction of it
anonymous
  • anonymous
how do u find that
triciaal
  • triciaal
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)
anonymous
  • anonymous
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.
anonymous
  • anonymous
and the direction of it opens up
anonymous
  • anonymous
is that correct?
anonymous
  • anonymous
can i plz have the complete answer
triciaal
  • triciaal
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
anonymous
  • anonymous
can i have the answer for the example u provided
anonymous
  • anonymous
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
triciaal
  • triciaal
you need to slow down and read the responses I even gave you the picture of the graph for the example I used
anonymous
  • anonymous
for the example u used i just want to know what the direction of it is and the y intercepts and zeros
anonymous
  • anonymous
and ok
triciaal
  • triciaal
the equation for the axis of symmetry x = -3/2
triciaal
  • triciaal
LOOK AT THE GRAPH
anonymous
  • anonymous
so it opens up?
anonymous
  • anonymous
yes or no
anonymous

thanks anyways
