Answer:
x^2-4x+3
Step-by-step explanation:
Since the zeroes of the quadratic are 1 and 3, we can set up an equation in factored form:
(x-1)(x-3)
=x^2-4x+3
We can further check that this is the right answer by evaluating it at the vertex:
(2)^2-4*2+3=-1
Since that corresponds to the graph, the answer is x^2-4x+3
Answer:
D) Rotation of 180 degrees about its center.
Step-by-step explanation:
because when you turn that shape in 180 degres is going to be in the same coordinates.
C because i did it and got it right
Answer:
<em>y = -3x + 2</em>
Step-by-step explanation:
From the graph, you see the line intersects the y-axis at y = 2, so the y-intercept is b = 2.
Now we need the slope. We need to find the number of vertical and horizontal units to go from one point to the other. Starting at point (-1, 5), go down 6 units and then go right 2 units. The change in y is -6. The change in x is 2. slope = m = (change in y)/(change in x) = -6/2 = -3.
m = -3; b = 2
y = mx + b
y = -3x + 2
