Q. Use the following function rule to find f(16).f(x)=4xf(16)=_____
Identify Function and Input: Identify the function and the input value.We are given the function f(x)=4x 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)=4x.f(16)=416
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 4.f(16)=4×4
Simplify Final Answer: Simplify the expression to find the final answer. f(16)=16
