Question

use the equation f(s)=8s+15 to evaluate the function at each value. explain what each means in terms of the problem

Answer 1

To evaluate the function f(s) = 8s + 15, substitute each given value for s and calculate the result. The outputs for s=7, 100, 11, 0, and 2.5 are 71, 815, 103, 15, and 35, respectively, and they represent the function's output for each input value.

To evaluate the function f(s) = 8s + 15 at each given value, simply replace the variable s with the specified value and perform the arithmetic operation.

1. f(7) would be calculated as 8(7) + 15, which equals 56 + 15, giving us a result of 71.
2. f(100) is 8(100) + 15, which equals 800 + 15, resulting in 815.
3. f(11) is computed as 8(11) + 15, which is 88 + 15, totaling 103.
4. f(0) is simply 8(0) + 15, and since 8 times 0 is 0, we are left with just 15.
5. f(2.5) is 8(2.5) + 15, where 8 times 2.5 is 20, so we add 15 to get a total of 35.

Each evaluation of the function represents the output value of f(s) when s is replaced with the given input. This output value could represent anything depending on the context of the problem, such as the cost of an item, the number of points a team scores, etc.

Answer 2

Well, the function is an equation used to find slope, called slope-intercept form: y=mx+b f(s) being y, 8 being the slope or m, s being the x coordinate, and 15 being b or the y-intercept.
