Q. Use the following function rule to find f(16).f(x)=5xf(16)=_____
Identify Function and Input: Identify the function and the input value.We are given the function f(x)=5x and we need to find the value of f(16).
Substitute Input into Function: Substitute the input value into the function.To find f(16), we substitute x with 16 in the function f(x)=5x.f(16)=516
Calculate Square Root: Calculate the square root of the input value.The square root of 16 is 4, since 4×4=16.16=4
Multiply by Coefficient: Multiply the square root by the coefficient.Now, we multiply the square root we found by the coefficient 5.f(16)=5×4
Perform Final Multiplication: Perform the multiplication to find the final answer.f(16)=20
