Given Function: Given the function f(x)=−x2−10x−15, we need to find the value of f(2). This means we will substitute x with 2 in the function and simplify.
Substitute x with 2: Substitute x with 2 in the function:f(2)=−(2)2−10(2)−15
Calculate and Multiply: Calculate the square of 2 and multiply 10 by 2:f(2)=−(4)−(20)−15
Simplify Expression: Simplify the expression by performing the arithmetic operations: f(2)=−4−20−15
Final Result: Add the numbers together to get the final result:f(2)=−4−20−15=−39
