Q. Use the following function rule to find f(123).f(x)=6172−xf(123)=_____
Identify Function Rule: Identify the function rule and the input value.We are given the function rule f(x)=6172−x and we need to find the value of f(123).
Substitute Input Value: Substitute the input value into the function.To find f(123), we substitute x with 123 in the function rule:f(123)=6172−123
Perform Subtraction: Perform the subtraction inside the square root.Calculate the value inside the square root:172−123=49
Calculate Square Root: Calculate the square root.Find the square root of 49:49=7
Multiply by 6: Multiply the result by 6. Now, multiply the square root by 6 to find f(123): f(123)=6×7
Complete Calculation: Complete the calculation.Perform the multiplication to get the final result:f(123)=42
