Answer:
B
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here the vertex = (- 2, - 3 ) , then
y = a(x - (- 2))² - 3 , that is
y = a(x + 2)² - 3
To find a, substitute any point on the graph into the equation
Using the coordinates of the y- intercept (0, 5 )
5 = a(0 + 2)² - 3 ( add 3 to both sides )
8 = a(2)² = 4a ( divide both sides by 4 )
2 = a
y = 2(x + 2)² - 3 → B
You multiply 9 times nine 6 times. ~9*9*9*9*9*9~
Answer:
Answer is 15-r .Hope it will help you
I would go with D.
Try drawing it out. When you do you realize that y=6 is a horizontal line and x=? would have to be a vertical line because a line that it x= anything is a vertical. Because we are not given the "?" the slope is undefined.
Answer:
domain = {0, 1, 2, 3}
range = {0, -1, -2, -3}
Step-by-step explanation:
The function is the set of ordered pairs (0, 0), (1, -1), (2, -2). (3, -3)
The domain is the set of x values. So, domain = {0, 1, 2, 3}
The range is the set of y values. So, range = {0, -1, -2, -3}
