Transcript text: Find the indicated values for the function $f(x)=\sqrt{2 x-10}$.
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
A. $f(10)=$ $\square$ (Round to the nearest hundredth as needed.)
B. The function value is not a real number.
Solution
Solution Steps
To solve for the indicated values of the function f(x)=2x−10:
Substitute the given value of x into the function.
Calculate the expression inside the square root.
Take the square root of the result.
Round the final answer to the nearest hundredth if necessary.
Step 1: Evaluate f(10)
To find f(10), we substitute x=10 into the function f(x)=2x−10:
f(10)=2(10)−10
Step 2: Simplify the Expression
Now, we simplify the expression inside the square root:
