What is the image of the point (2,-3) after a rotation of 90 ∘ counterclockwise about the origin?

(2,-3) changes to (3,2)

A is correct.

Step-by-step explanation:

Given: The point (2, −3) after a counterclockwise rotation of 90° about the origin.

Rotation is counterclockwise about origin.

We are given coordinate

We can see in diagram also. Please see the attachment for rotation.

Hence, (2,-3) changes to (3,2

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

false
