When 144 is squared, it is equal to 12.
Answer:
(2)
Step-by-step explanation:
Answer:
below the x-axis
Step-by-step explanation:
y=x^2+2x-3
the vertex is located on the axis of symmetry
h
to find h ax^2 +bx+c
h= -b/2a = -2/2(1) = -1
the x coordinate of the vertex is -1
to find the y coordinate, substitute into the equation
y = (-1)^2 +2(-1) -3
= 1-2-3
= -4
(-1,-4)
the vertex is below the x axis
I believe C is the correct answer.
Because y should be graphed as positive, or to the right, ruling out option B. In option A the dashed line representing the second inequality is incorrect, so C is your answer.
