A quadratic function is given.
f(x) = 2x2 + 6x
(a) Express the quadratic function in standard form. 
f(x) =
2x2+6x=0
 

(b) Find its vertex and its x- and y-intercept(s). (If an answer does not exist, enter DNE.)
vertex    (xy) =
 
32 , −92 
  
x-intercepts    (xy) =
 
3

Thank you for the opportunity to help you with your question! the solution is as such:

The standatd form is y= 2( x + 1.5)^2  - 2.25

The vertex is (-1.5 , - 2.25)


The x intercept is - 0.75

The y intecept is = 2.25


Please let me know if you need any clarification. I'm always happy to answer your questions.awaiting a positive feedback. It was lovely helping you. in case of a wrong answer or doubt please discuss before taking any action. Please do contact or tex
