Answer:

The coordinates of B will be (3,-4).

Step-by-step explanation:

If a point on the coordinate plane reflects across the y-axis then its y-coordinate will not alter but the x-coordinate will change by its sign only.

Now, if B'(-3,-4) is the image of B after a reflection in the y-axis then we can say B is the image point when the original point is B'(-3,-4) after reflection in the y-axis.

Therefore, the coordinates of B will be (3,-4). (Answer)

PLEASE HELP ME WITH THIS MATHS QUESTIONS!!!<br> WILL GIVE BRAINLIEST!!!
vampirchik [111]

Answer:

a) y = (x+2)/3

b) 5

Step-by-step explanation:

f^-1(x) means "f inverse of x". To find the inverse, we simply:

a ) f(x) = 3x -2

    y = 3x - 2 --> because f(x) is the same thing as y

    x = 3y - 2 --> to find the inverse, we simply just switch x and y

    x + 2 = 3y

    y = (x+2)/3

b) f^-1(13)

   f^-1(13) = [((13) + 2)/3]

   f^-1(13) = (15)/3

   f^-1(13) = 5
