Final answer:
The value of the function F(x) evaluated at F(-3) is -6.
Step-by-step explanation:
To find the value of the function F(x) evaluated at F(-3), we substitute -3 in place of x in the function expression.
So, F(-3) = 2(-3)² + 5(-3) - 9
Simplifying the expression:
- F(-3) = 2(9) - 15 - 9
- F(-3) = 18 - 15 - 9
- F(-3) = 3 - 9
- F(-3) = -6
Therefore, the value of the function F(x) evaluated at F(-3) is -6.
