What type of transformation transforms (a, b) to (-a, b)? a reflection over the y-axis
a translation of 1 unit down
a reflection over the x-axis
a translation of 1 unit up

A reflection over the y axis .

Step-by-step explanation:

Given  : Transforms (a,b) to (-a,b).

To find : What type of transformation.

Solution : We have given

Parent function : (a,b) .

Transformed  : (-a ,b).

Transformation rule of reflection over y axis : ( x, y) →→ ( -x ,y).

Then we can say in transformation (a,b) →→→→ (-a,b).

Therefore, A reflection over the y axis

Step-by-step explanation:

plz brain list

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

answer: d. $20
