Answer:

j^-1(x) = 1/2(x+5)

Step-by-step explanation:

1. Replace j(x) with y to make it easier

y = 2x - 5

2. Switch the places of x and y

x = 2y - 5

3. Solve for y

x + 5 = 2y

y = 1/2(x+5)

4. Replace y with j^-1(x)

j^-1(x) = 1/2(x+5)

What is the image of the point (–3, 4) after a rotation of 90° counterclockwise about the point (–3, 0)?
Snowcat [4.5K]
Initially, the point (-3,4) is in the second quadrant of the cartesian plane. If the rotation is about point (-3,0) at 90 degrees, you find a point that when connected to (-3,4) makes two lines perpendicular to each other. Since the direction is counterclockwise, you move 3 points to the left, then 4 points down. That would be (-7,0). The answer is A.
