Final answer:
To calculate g(3) for g(x) = -5x²², substitute 3 for x resulting in g(3) = -405.
Step-by-step explanation:
To calculate the value of the function g(x) = -5x²² at x = 3, you need to substitute the value of x into the function.
The calculation will look like this:
- g(3) = -5(3)²²
- g(3) = -5(9)
- g(3) = -5*81
- g(3) = -405
So, g(3) is equal to -405.
