Question

The graph of which quadratic equation is shown below?


y = -x2 - 4x + 3 14 years ago

Answer 1

No, y = -x^2-4x+3 is not the answer

Answer 2

This graph shown opens upwards while your answer has a graph that will open downwards.

Answer 3

y = x2 + 4x - 3
y = x2 - 4x + 3
y = -x2 + 4x - 3
y = -x2 - 4x + 3

Answer 4

Roots are x = 1 and x = 3, so


x = 1 or x = 3


x-1 = 0 or x-3 = 0


(x-1)(x-3) = 0


x^2 - 4x + 3 = 0


So the answer is choice B

Answer 5

And it turns out that the y-intercept is (0,3) which is the y-intercept for y = x^2 - 4x + 3, so that works out
