Answer 1

[AI-generated answer — Explain Bot]

To find the value of the function y = 3x^2 - 21 when x = 4, we substitute the value of x into the equation and calculate the result.

Step 1: Replace x with 4 in the equation.
y = 3(4)^2 - 21

Step 2: Simplify the equation.
y = 3(16) - 21
y = 48 - 21
y = 27

Therefore, when x = 4, the value of the function y = 3x^2 - 21 is 27.
