State the axis of symmetry and vertex of the following quadratic function. Show all work. x^2=144 Please help, my teacher didn't really go over this, I'm really confused. Thanks...

Spiderman crawls along the edges of a unit cube. Each time he gets to a vertex, he chooses one of the three edges leaving that vertex. How many of the 81 paths of length 4 lead back to the original...

What is the equation of the parabola with vertex (-5, 4) and focus (-2, 4)?

write the quadratic function the form f(x)=a(x-h)^2+k then, give the vertex of its graph quadratic function given: f(x)=3x^2+30x+74

A. Y=5(x+28)^2 -11 B. X=5(y+11)^2 -28 C.y=-5(x+11)^2 -28 D.x=-5(y+28)^2 -11

Wats the. Vertex

Y = x2 - 9

f(x)=x2+6x-4 If the parabola described above is shifted m units to the right and n units up, the new vertex is (5,-6). What's the value of mn-1?

please help

Vertex form is y = a(x - h)^2 + k. If a quadratic function has the vertex form of y = 2(x + 5)^2 - 4, what is the vertex? Thank you

Ive been looking on the web but nothing comes up with it. most just say they already have the vertex

Find the vertex and the extreme value of the function f (x) = -3x^2-4x-1 The extreme value is the maximum or minimum value of a quadratic function. Be sure to leave your answer as a reduced...

Hi, this equation makes no sense. When I calculate the vertex I get (2,11) but my book is saying the answer is (2,3)? I don't understand how it can be (2,3) . This is what I did: (-b)/(2a)...

How would you write the quadratic function y = -3x² + 18x - 2 in vertex form? You'll need to calculate the vertex to find "h" and "k", and you'll need to use the value of "a"...

What is the vertex of the quadratic function y = -7x^2 + 28x - 5? Thank you!

Vertex form is y = a(x - h)^2 + k. If a quadratic function has the vertex form of y = 3(x + 7)^2 - 2, then what is the reflection point for the y-intercept? Thank you! ...

Hi i have been really stuck on my assignment for a while particularly this part where i need two find the vertex of a parabola given two points

f(x)=2x^2-x+1 what I did: 2x^2/2 - x/2 = -1/2 x^2 - x/2 = -1/2 x^2 - x/2 +1/16 = -1/2 +1/16 (x-1/4)^2= -7/16 Vertex: (1/4, 7/16) But when I graph...

Please explain answer with work/explanation. Very very confused. If the area of a rectangle is 126 square inches and the width of the rectangle is 7 inches shorter than the length, what...
