y=4x2 + 2x - 15

I am just curious which one would be the preferable option when graphing a parabola

A ball is thrown from 5 inches above the ground. After 2 seconds, the ball reaches a maximum height of 9 inches, and then lands back on the ground 5 seconds after it was thrown. Write a function that...

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

I got y=5x(x+2)^2-40 but as my answer but I feel like its wrong. Can someone please help me? Thank you!

find the vertex form for the quadratic function that passes through (4,12) and has a minimum at (2,-4)

i need help graphing

Put the function y = 7 x^2 + 14 x + 18 in vertex form f(x) = a(x-h)^2 + k and determine the values of a, h, and k.

Is there a different method other than completing the square to solve this?

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

6m^2=13m+28 (x-9)(x+8)=0 x^2-x-2=0 4x^2+8x-21=0

The height of a ball thrown from the top of a platform can be modeled by the equation f(x)=-16x2+6x-34, where f(x) is the height, in feet, x seconds after the ball was thrown. Complete the square...

Help me solve it plz nd show work

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! ...

Write the equation of the parabola in vertex form. vertex (2,2), point (3,-3)

Suppose g(x) = −2x2 +12x+4. Convert the quadratic function to vertex form by completing the square. Identify the vertex.
