Question

The graph of which quadratic equation is shown below?

a u-shaped graph on a coordinate plane that is opening up and has a vertex of (−1, −4)

y = x2 − 2x − 3

y = x2 + 2x − 3

y = −x2 + 2x − 3

y = −x2 − 2x − 3

Answer 1

the correct ans is the 2nd option.....

Answer 2

u can first easily eliminate the last two options..
becz as per the que.. the graph is opening upward means the coffeicient of x^2 is +VE
so now only two options are left
put the value of x and y and check the ans..

Answer 3

-4 = 1-2-3
-4=-4
