Evaluate the function for x = 3.5 f(x)=[2.5x]<br><br> a 8.75<br><br> b 8<br><br> c 9
RSB [31]

Answer:

The correct option is a. 8.75.

Step-by-step explanation:

Given:

f(x)=[2.5x] .............................. (1)

Where;

x = 3.5

The function can be evaluated by substituting x = 3.5 into equation (1), we have:

f(3.5) = 2.5 * 3.5

f(3.5) = 8.75

This implies the value of the function is 8.75. Therefore, the correct option is a. 8.75.
