Which phrase best describes the translation from the graph y = (x + 2)2 to the graph of y = x2 + 3?
Mashutka [201]

1. Consider the transformation that maps the graph of the function y=(x+2)^2 into the graph of the function y=x^2. This transmormation has a rule:

(x,y)→(x+2,y)

that is translation 2 units to the right.

2. Consider the transformation that maps the graph of the function y=x^2 into the graph of the function y=x^2+3. This transformation has a rule:

(x,y)→(x,y+3)

that is translation 3 units up.

Answer: correct choice is C.

given data:

ABC market share = 30%

number of customers surveyed = 800

probability that more than 32% prefers ABC

p ( x ≥ 256 )

= 1 - ( 256/800 )

Can someone answer my question plz
kirill115 [55]

Answer:

Draw a straight line through these two points (0, 0) and (1, 3).

Step-by-step explanation:

"Proportional relationship" implies line or curve that goes through the origin; there is no "y-intercept" in this case.  

Plot a dot at (0, 0).  Next, move your pencil point 1 unit to the right (you'll end up at (1, 0), and then move it from there up to (1, 3).  Draw a straight line through these two points (0, 0) and (1, 3).
