Answer:
C
Step-by-step explanation:
The identity property for addition tells us that zero added to any number is the number itself.
Answer:
See explanation below to use the vertex form to solve a quadratic equation.
Step-by-step explanation:
(x - h)^2 - k = 0, the vertex is (h, -k)
An example below, taking a quadratic equation and completing the square:
x^2 - 2x - 1 = 0
x^2 - 2x = 1
(-2/-2)^2 = 1, add 1 to both sides of the equation.
x^2 - 2x + 1 = 1 + 1
(x - 1)^2 = 2
(x - 1)^2 - 2 = 0
The vertex is (1, -2)
Answer:
Step-by-step explanation:
the x intercepts are -1 and 1 (where y = 0)
the y intercept is 1 (where x = 0)
