Q. Use the following function rule to find f(121).f(x)=6+2xf(121)=_____
Identify Function and Input: Identify the function and the input value.We are given the function f(x)=6+2x and we need to find the value of f(121).
Substitute Input into Function: Substitute the input value into the function.To find f(121), we substitute 121 for x in the function:f(121)=6+2121
Calculate Square Root: Calculate the square root of 121. The square root of 121 is 11, since 11×11=121.
Continue Calculation with Result: Continue the calculation with the square root result.Now that we know 121=11, we can continue the calculation:f(121)=6+2×11
Multiply and Calculate: Multiply 2 by 11. 2×11 equals 22. f(121)=6+22
Add for Final Result: Add 6 to 22 to get the final result.6+22 equals 28.f(121)=28
