Question

Let me add the picture of the graph c:

Choose the equation below that corresponds to the graph shown.



y = 2x2 + 8x − 3

y = −2x2 + 8x − 3

y = 2x2 − 8x − 3

y = −2x2 − 8x − 3

Answer 1

y = −2x^2 + 8x − 3

Answer 2

a parabola with - sign in x2 term will be down wards

Answer 3

well m not very sure on formula of Parabola,

But in this type of questions, what you can do is , take a point, substitute its x & y co - ordianates in equation`s and get ur answer..

overe here its x = 02 and y = 5..

so graph would be..

y = −2x2 − 8x − 3 .. as the equation is balanced if we put -2 and 5..
