the graph of y = x² + 3 is obtained by moving the graph of y = x²

a. 3 unitd to the right
b. 3 units to the left
c. 3 units upward
d.3 units downward​

The answer is C. 3 units upward.

Explanation:

y = x² + 3 is in vertex form of a quadratic equation. Wherein, the vertex form has a pattern of y = a(x + h)^2 + k. Furthermore, h is the horizontal change/shift, and k is the vertical change/shift. In y = x² + 3, 3 is the k, meaning the graph y = x² will move 3 units upward. Why upward? 3 is a positive integer, not a negative integer. If a number/integer is negative, the movement will be downward.

- I hope this can help you a lot.
