The correct answer is "negative 4 plus 3i".
Based on the information given, the point A is graphed 4 units to the left and 3 units up from the complex plane's origin.
To find the complex number represented by point A, we can use the convention that the horizontal axis represents the real part of a complex number, and the vertical axis represents the imaginary part.
Since point A is 4 units to the left, the real part would be negative. And since point A is 3 units up, the imaginary part would be positive.
Therefore, the complex number represented by point A on the complex plane is "negative 4 plus 3i." So the correct answer is "negative 4 plus 3i."
