Define a function f(x)=60x+240 for all positive real values x. What is the function value for x=31.3? Round your answer to 2 decimal places.
Question
Define a function
f(x) = 60x + 240
for all positive real values x.
What is the function value for x = 31.3?
Round your answer to 2 decimal places.
Solution
To find the function value for x=31.3, you need to substitute x with 31.3 in the function f(x)=60x+240.
Step 1: Substitute x with 31.3 in the function f(x)=60x+240. f(31.3) = 60(31.3) + 240
Step 2: Multiply 60 by 31.3. 60 * 31.3 = 1878
Step 3: Add 240 to the result from step 2. 1878 + 240 = 2118
So, the function value for x=31.3 is 2118.
However, you asked to round the answer to 2 decimal places. Since our answer is a whole number, it will remain the same even after rounding.
So, the function value for x=31.3, rounded to 2 decimal places, is 2118.00.
