Question

If the function S (x) is defined by S(x) = -- then which of the following is the value of S(10)?

a. 14
b. 2
c. 7

Answer 1

The function S(x) = -x + 7. To find the value of S(10), substitute x = 10 into the function S(x). Therefore, S(10) = -(10) + 7 = -10 + 7 = -3. Option c

Step-by-step explanation:

The function S(x) = -x + 7 is defined with the equation, where x represents the input variable. To find S(10), substitute the value x = 10 into the function to determine the output for this specific input. Thus, S(10) = -10 + 7 = -3.

The computation is carried out by replacing the x in the function S(x) with the value 10, resulting in S(10) = -10 + 7. This arithmetic operation simplifies to S(10) = -3. Therefore, when the value x = 10 is inputted into the function S(x), the output or value of the function S is -3.

In conclusion, the function S(x) = -x + 7 yields an output of -3 when x is equal to 10. This computation provides the specific value of the function for the given input, demonstrating the process of evaluating a function at a particular value.Option c
