Q. Use the following function rule to find f(49).f(x)=x−1f(49)=_____
Identify function rule and input: Identify the function rule and the input value.The function rule given is f(x)=x−1, and we need to find the value of f(49).
Substitute input into rule: Substitute the input value into the function rule.To find f(49), we substitute 49 for x in the function rule:f(49)=49−1
Calculate square root: Calculate the square root of the input value.The square root of 49 is 7, so we have:f(49)=7−1
Subtract to find final value: Subtract 1 from the square root to find the final value.f(49)=7−1f(49)=6
