Answer: B

Step-by-step explanation:

y=x+6

y=-2x-3

x+6=-2x-3

Add 2x to both sides

3x+6=-3

Subtract 6 from both sides

3x=-9

Divide 3 from both sides

x=-3

Put into equations

y=-3+6

y=3

The graph of y = x^2 is translated 1 unit to the right. What is the equation of the new graph?

Burka [1]

Answer: 2

Step-by-step explanation:

If the number was OUTSIDE the exponents it represents a movement up or down

If the number is inside the parenthesis and exponent ex: (x-1)^2 then it decides a movement on the left or right

However inside the parenthesis it is reversed, so a - is move to the right and a + is moved to the left, this making your answer (x-1)^2
