Answer:
y= 2x² + 2x +3
Step-by-step explanation:
y=f(x)
y=2( x^2 + 1^2 +2(x)(1) ) + 3
y=2x^2 + 1 + 2x +3
y= 2x^2 + 2x +3
Answer:
D
Step-by-step explanation:
They all move 1 unit up.
The mapping notation essentially tells you, what you do to each point to get the image point.
In this case (x,y)→(x,y+1) is telling you, for any given coordinate on the original, you add 1 to its y coordinate. Adding 1 to a y coordinate moves it up one unit.
The correct answer is (2, 1). ( I took the test :) )
Answer:
Right angle
