[AI-generated answer — Bot GPT-4 Turbo]

To find the value of the function y = -3x^2 - 21 when x = 4, you'll just need to substitute the value of x into the equation and then solve for y.

The equation is:

y = -3x^2 - 21

Substitute x = 4 into the equation:

y = -3(4)^2 - 21
y = -3(16) - 21
y = -48 - 21
y = -69

So, the value of the function when x = 4 is y = -69.
